Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a precision drilling and positioning device for electromechanical equipment. Background Technology

[0002] The precision drilling positioning device for electromechanical equipment is an automated device designed to improve the accuracy and efficiency of drilling operations. This device is mainly used in the field of electromechanical equipment manufacturing, especially in situations where high-precision drilling operations are required.

[0003] Existing patent CN214443198U discloses a precision drilling and positioning device for electromechanical equipment, including a device platform and a drilling device. A support is fixedly mounted on the surface of the device platform, and a positioning platform is fixedly mounted above the support. The positioning platform has two support plates on its surface, with grooves formed on the inner side of each support plate. This invention utilizes a longitudinal slide rail that slides vertically on a lifting frame, a transverse slide rail that slides forward and backward within the longitudinal slide rail, and a drilling device mounted on a mounting block that slides left and right within the transverse slide rail. By controlling an electric push rod and two servo motors via a controller, the drilling device on the mounting block can be accurately and quickly positioned above a designated drilling location. The drilling device then precisely drills holes in a circuit board fixed to the positioning platform.

[0004] This patent solves the problem of circuit board misalignment during drilling. The above technical solution achieves precise drilling of circuit boards by setting slide rails and positioning tables. However, the above solution also has the problem of wobble when fixing the clamping plate during drilling of the front cover of the motor. Specifically, due to its shape characteristics, wobble often occurs when fixing the front cover of the motor with clamping plates during drilling. This wobble not only affects the drilling accuracy but may also damage the workpiece, reducing production efficiency and product quality. Therefore, this utility model proposes a precision drilling and positioning device for electromechanical equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a precise drilling and positioning device for electromechanical equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision drilling and positioning device for electromechanical equipment, comprising a housing, wherein the top of the housing is provided with a first sliding groove and a recess, and the inner cavity of the recess is provided with an inner support component;

[0007] The internal support assembly includes a first push rod, a support ring at the top of the first push rod, a top plate at the top of the output end of the first push rod, a first fixing block at the bottom of the top plate, a second connecting rod on the side of the first fixing block, a second fixing block at the end of the second connecting rod away from the first fixing block, a second support plate at one end of the second fixing block, a third support plate on one side of the second support plate, a third fixing block on the other side of the second support plate, a third connecting rod on the side of the third fixing block, and a fourth fixing block at the end of the third connecting rod away from the third fixing block.

[0008] In a preferred embodiment, a chip removal assembly is provided on the top of the housing, the chip removal assembly includes a first fan, a first filter is provided on the side of the first fan, and a collection groove is provided on the side of the housing.

[0009] The technical effects of adopting the above-mentioned further solution are as follows: by setting a first fan, the debris formed after drilling can be blown away; by setting a first filter screen, the debris can be prevented from entering the first fan; and by setting a collection trough, the debris can be collected.

[0010] In a preferred embodiment, the inner cavity of the housing is provided with a clamping assembly, the clamping assembly including a mounting plate, a first support plate at the bottom of the mounting plate, a first connecting rod at the top of the mounting plate, a first slider at the end of the first connecting rod away from the mounting plate, a first connecting rod at the bottom of the first slider, and a gripper at the bottom of the first connecting rod.

[0011] The technical effect of adopting the above-mentioned further solution is as follows: the mounting plate is rotatably connected to the first support plate through a bearing, and a motor is provided on the top of the mounting plate. When the motor is started, the output shaft of the motor rotates forward, thereby driving the mounting plate to rotate. When the mounting plate rotates, it can drive the first connecting rod to rotate. When the first connecting rod rotates, it can drive the first slider to move. When the first slider moves, it can drive the gripper to move through the first connecting rod, thereby clamping and fixing the workpiece.

[0012] In a preferred embodiment, the top of the first support plate is provided with a second sliding groove, the side of the first slider is provided with a third sliding groove, and the inner wall of the second sliding groove is provided with a second slider.

[0013] The technical effect of adopting the above-mentioned further solution is that the second slide groove is the same size as the groove, and the third slide groove cooperates with the second slider, thereby enabling the first slider to move along the inner cavity of the second slide groove and avoiding deviation of the movement trajectory of the first slider.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By activating the first push rod, the output end of the first push rod moves downward, which in turn drives the top plate downward. The downward movement of the top plate drives the first fixed block downward, which in turn drives the second connecting rod downward. The support ring is fixedly connected to the first push rod, and the middle sections of the second and third connecting rods are rotatably connected. When one end of the second connecting rod is subjected to force, this force is transmitted along the connecting rod and generates rotational motion at the connection point with the third connecting rod, thus forming a thrust. The cooperation of the second and third connecting rods enables the second and third fixed blocks to drive the second support plate outward, thereby achieving the effect of internal support and positioning of the hole at the top of the motor front cover. Through the cooperation of the third support plate and the lifting assembly, the motor front cover can be lifted. The cooperation of the third support plate and the clamping assembly prevents damage to the housing during drilling. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment provides a technical solution: a precision drilling and positioning device for electromechanical equipment, including a housing 1, the top of the housing 1 is provided with a first sliding groove 11 and a groove 12, and the inner cavity of the groove 12 is provided with an inner support component 4.

[0029] The inner support assembly 4 includes a first push rod 41, a support ring 42 at the top of the first push rod 41, a top plate 43 at the top of the output end of the first push rod 41, a first fixing block 44 at the bottom of the top plate 43, a second connecting rod 45 on the side of the first fixing block 44, a second fixing block 46 at the end of the second connecting rod 45 away from the first fixing block 44, a second support plate 47 at one end of the second fixing block 46, a third support plate 48 on one side of the second support plate 47, and a third fixing block 49 on the other side of the third fixing block 49. A third connecting rod 410 is provided, and a fourth fixing block 411 is provided at the end of the third connecting rod 410 away from the third fixing block 49. A fourth sliding groove 412 is provided on the side of the second fixing block 46. A second connecting rod 413 is provided on the side of one end of the second connecting rod 45. One end of the second connecting rod 413 extends into the inner cavity of the fourth sliding groove 412 and is slidably connected to the fourth sliding groove 412. When the first push rod 41 is activated, the output end of the first push rod 41 moves downward, which can drive the top plate 43 to move downward. When the top plate 43 moves downward, it can drive the first fixing block 44 to move downward. When the first fixed block 44 moves downward, it can drive the second connecting rod 45 to move downward. The support ring 42 is fixedly connected to the first push rod 41. The second connecting rod 45 and the third connecting rod 410 are rotatably connected at the middle. When one end of the second connecting rod 45 is subjected to force, this force will be transmitted along the connecting rod to the other end of the second connecting rod 45, and a rotational motion will be generated at the connection with the third connecting rod 410, thereby forming a thrust. When the other end of the second connecting rod 45 moves outward, the fourth sliding groove 412 and the second connecting rod 413 cooperate to limit its movement trajectory and prevent the second connecting rod 45 from moving outward. When a deviation occurs, the second link 45 and the third link 410 cooperate to drive the third fixed block 49 and the second fixed block 46 to move outward. When the third fixed block 49 and the second support plate 47 move outward, they can drive the second support plate 47 to move outward, thereby achieving the effect of internal support positioning of the hole at the top of the motor front cover. When it is necessary to drill a hole at the top of the motor front cover, after the internal support positioning is completed, by setting the third support plate 48, the motor front cover can be lifted up when the lifting component 5 drives the internal support component 4 to rise, so as to avoid damage to the housing 1 during drilling.

[0030] Going further, such as Figure 1 , Figure 2 and Figure 3As shown: A chip removal assembly 2 is provided on the top of the housing 1. The chip removal assembly 2 includes a first fan 21. A first filter screen 22 is provided on the side of the first fan 21. A collection groove 23 is provided on the side of the housing 1. A clamping assembly 3 is provided in the inner cavity of the housing 1. The clamping assembly 3 includes a mounting plate 31. A first support plate 32 is provided at the bottom of the mounting plate 31. A first connecting rod 33 is provided at the top of the mounting plate 31. A first slider 34 is provided at the end of the first connecting rod 33 away from the mounting plate 31. A first connecting rod 35 is provided at the bottom of the first slider 34. The bottom is provided with a gripper 36, the top of the first support plate 32 is provided with a second slide groove 37, the side of the first slider 34 is provided with a third slide groove 38, the inner wall of the second slide groove 37 is provided with a second slider 39, the bottom of the first push rod 41 is provided with a lifting assembly 5, the lifting assembly 5 includes a second push rod 51, the bottom of the second push rod 51 is provided with a support frame 52. First, the front end cover of the motor to be drilled is placed in the middle of the housing 1. By starting the lifting assembly 5, the inner support assembly 4 can be driven to move upward. When the inner support assembly 4 moves upward to a certain position, the first... A push rod 41 allows the inner support assembly 4 to internally support the hole at the top of the motor front cover. Continuing to operate the second push rod 51 lifts the motor front cover, preventing damage to the housing 1 during drilling of the workpiece. The second slide groove 37 is the same size as the groove 12. The mounting plate 31 is rotatably connected to the first support plate 32 via bearings. A motor is mounted on the top of the mounting plate 31. Starting the motor causes its output shaft to rotate forward, thus rotating the mounting plate 31. The rotation of the mounting plate 31 drives the first connecting rod 33 to rotate. When rod 33 rotates, it can drive the first slider 34 to move. When the first slider 34 moves, the third slide groove 38 and the second slider 39 cooperate, so that the first slider 34 can move along the inner cavity of the second slide groove 37, avoiding deviation of the movement trajectory of the first slider 34. When the first slider 34 moves, it can drive the gripper 36 to move through the first connecting rod 35. The gripper 36 cooperates with the inner support assembly 4, so as to clamp and fix the front end cover of the motor, avoiding the workpiece from shifting and causing damage when drilling the front end cover of the motor.

[0031] Working principle:

[0032] like Figure 1-5 As shown:

[0033] In use: First, place the motor front cover that needs drilling in the middle of the housing 1. Start the second push rod 51. The output end of the lifting component 5 drives the inner support component 4 to move upward. When the inner support component 4 moves to a certain position, start the first push rod 41. The output end of the first push rod 41 moves downward, thereby driving the top plate 43 downward. When the top plate 43 moves downward, it can drive the second connecting rod 45 downward through the first fixed block 44. When one end of the second connecting rod 45 is subjected to force, this force will be transmitted along the connecting rod to the other end of the second connecting rod 45, and a rotational motion will be generated at the connection with the third connecting rod 410, thereby forming a thrust. Through the cooperation of the second connecting rod 45 and the third connecting rod 410, the second support plate 47 can be driven outward through the third fixed block 49 and the second fixed block 46. The second support plate 47 and The inner wall of the hole at the top of the motor front cover contacts the motor front cover, thus achieving the effect of internal support and positioning of the motor front cover. After the motor front cover is positioned, the second push rod 51 continues to run, and the third support plate 48 contacts the inner cavity of the motor front cover, thereby lifting the motor front cover and starting the motor set at the bottom of the mounting plate 31. The output shaft of the motor rotates forward, thereby driving the mounting plate 31 to rotate. When the mounting plate 31 rotates, it can drive the first slider 34 to move through the first connecting rod 33. When the first slider 34 moves, it can drive the gripper 36 to move through the first connecting rod 35. The gripper 36 and the inner support assembly 4 cooperate to clamp and fix the motor front cover. After the drilling work of the motor front cover is completed, the first fan 21 is started to blow the debris into the inner cavity of the collection tank 23 for collection.
