Description

Technical Field

[0001] This invention relates to the field of drilling technology, and more particularly to a motor housing processing device. Background Technology

[0002] As the core protective and load-bearing component of the motor, the motor housing usually has mounting lugs on its outer side for assembling and fixing the whole machine.

[0003] In existing technologies, traditional motor housing positioning fixtures used in drilling operations often employ a rigid, integral clamping method. This means the clamping points cannot flexibly avoid irregularly shaped structures such as heat sinks and mounting lugs on the outside of the motor housing. During clamping, the positioning blocks are highly susceptible to squeezing the heat sinks, causing deformation or breakage, or impacting the edges of the mounting lugs, resulting in structural damage.

[0004] Furthermore, the outer wall of the motor housing is densely covered with heat sinks. The gaps between the heat sinks are narrow and the structure is complex. Metal shavings generated during drilling are very easy to fall off and accumulate deep in the gaps, making it difficult to clean thoroughly using conventional blowing and wiping methods.

[0005] Therefore, we propose a motor housing processing device. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a motor housing processing device.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a motor housing processing device, comprising a housing, a drilling mechanism provided on the front surface of the housing, a base fixedly installed at the lower end of the front surface of the housing, two relatively symmetrically movable fixed side plates installed on the upper surface of the base through a transverse telescopic mechanism, a rotating side plate rotatably connected to the front end of the fixed side plate, an adjusting rod rotatably passing through the opposite ends of the fixed side plate and the rotating side plate, clamping flaps fixedly connected to the upper and lower ends of the adjusting rods, a positioning block fixedly connected to the end of the clamping flap away from the adjusting rod, a soft block fixedly connected to the side of the clamping flap away from the moving plate, and a locking mechanism provided on the upper surfaces of the fixed side plate and the rotating side plate;

[0008] The end of the rear adjusting rod is set with two sets of clamping petals and positioning blocks, and the ends of the two rear positioning blocks are fixedly connected by the lower connecting block;

[0009] When the locking mechanism is locked, the surface of the adjusting rod is adjusted, and the angle between the fixed side plate and the rotating side plate is limited.

[0010] Preferably, the drilling mechanism includes a vertically moving shell mounted on the front surface of the housing via a lifting mechanism. A drive motor is fixedly mounted on the upper surface of the vertically moving shell. Three transmission shafts are rotatably mounted on the inner side of the vertically moving shell. Transmission gears are fixedly mounted on the outer surface of the transmission shafts and the output shaft end of the drive motor, respectively. The transmission shafts and the output shaft of the drive motor are driven by meshing transmission gears. Three connecting frames are fixedly connected to the lower end of the vertically moving shell. A drill bit is rotatably embedded on the inner side of each connecting frame. The upper end of each drill bit is connected to the lower end of the transmission shaft via a universal transmission rod.

[0011] Preferably, the lifting mechanism includes a vertical cylinder fixedly installed at the bottom of the machine housing, a lifting plate fixedly connected to the telescopic end of the vertical cylinder, the lifting plate slidingly engaging with the machine housing in a vertical direction, and the front end of the lifting plate fixedly connected to the vertical moving shell.

[0012] Preferably, the telescopic mechanism includes a support frame fixedly installed on the upper surface of the base. Transverse guide plates are fixedly connected to both sides of the support frame. A movable plate is slidably sleeved on the outer surface of each side of the transverse guide plate. The telescopic ends of the transverse cylinders are fixedly connected to the movable plates on both sides. One end of the transverse cylinder is fixedly connected to the side surface of the support frame. One side surface of the fixed side plate is fixedly connected to the front end of the movable plate. A three-way seat is fixedly installed on the upper surface of the base near the front of the support frame.

[0013] Preferably, the locking mechanism includes a notch formed at the front end of the fixed side plate, the rear end of the rotating side plate being rotatably engaged into the inner side of the notch, a rotating column being fixedly inserted through the rear end of the rotating side plate, the rotating column being rotatably inserted through the inner side of the notch, a pressure plate being threaded onto the upper end of the rotating column, the pressure plate being pressed against the upper surface of the fixed side plate, and transverse locking components being respectively provided on the upper surfaces of the fixed side plate and the rotating side plate.

[0014] Preferably, the transverse locking component includes a sliding bar slidably connected to the upper surfaces of the fixed side plate and the rotating side plate respectively. A slider is fixedly connected to the lower surface of the sliding bar. Slide grooves are respectively formed on the upper surfaces of the fixed side plate and the rotating side plate. The slider slides into the inner side of the slide groove. A return spring is fixedly connected to the side of the slider near the adjusting rod. The end of the return spring is fixedly connected to the inner wall of the slide groove. A positioning gear is fixedly sleeved on the outer surface of the adjusting rod. A toothed opening is formed at one end of the sliding bar near the adjusting rod. The toothed opening meshes with the positioning gear.

[0015] Preferably, the lower surface edge of the pressure plate is provided with a beveled edge, and the upper surface of the pressure plate is fixedly connected with polygonal blocks.

[0016] Preferably, an anti-detachment ring is fixedly sleeved on the outer surface of the adjusting rod, and the anti-detachment ring is rotatably embedded in the inner side of the fixed side plate and the rotating side plate respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses a differentiated layout of multiple sets of positioning blocks. The front positioning block is positioned on both sides of the mounting lug, and the rear positioning block is limited in the front and rear positions of the mounting lug. Combined with the lower connecting block to avoid the bottom of the mounting lug, it can not only achieve multi-directional stable clamping of the motor housing, but also accurately avoid irregular and weak parts such as the motor heat sink and mounting lug.

[0019] 2. The present invention uses a protective design that fits the clamping flap and the soft block to cover the area above the heat sink of the motor housing around the mounting lug while positioning and clamping, forming a closed debris barrier layer to prevent metal debris generated during drilling from falling into the depth of the gap between the heat sink from the source.

[0020] 3. The present invention adopts a rotatable adjustment rod in combination with an angle-adjustable side plate structure, which can flexibly adapt to the installation lug position for positioning, accurately adjust the clamping distance and positioning angle, and ensure that the positioning block and soft block are tightly attached to the shell surface, greatly shortening the clamping and debugging time.

[0033] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0034] like Figures 1-11 The motor housing processing device shown includes a housing 1. A drilling mechanism is provided on the front surface of the housing 1. A base 2 is fixedly installed at the lower end of the front surface of the housing 1. Two relatively symmetrically movable fixed side plates 8 are installed on the upper surface of the base 2 through a transverse telescopic mechanism. A rotating side plate 9 is rotatably connected to the front end of the fixed side plate 8. An adjusting rod 10 is rotatably passed through the opposite ends of the fixed side plate 8 and the rotating side plate 9. A clamping flap 11 is fixedly connected to the upper and lower ends of the adjusting rod 10. A positioning block 12 is fixedly connected to the end of the clamping flap 11 away from the adjusting rod 10. A soft block 13 is fixedly connected to the side of the clamping flap 11 away from the moving plate 7. A locking mechanism is provided on the upper surfaces of the fixed side plate 8 and the rotating side plate 9.

[0035] The end of the rear adjusting rod 10 is configured with two sets of clamping petals 11 and positioning blocks 12, and the ends of the two rear positioning blocks 12 are fixedly connected by the lower connecting block 14.

[0036] When the locking mechanism is locked, the surface of the adjusting rod 10 is locked, and the angle between the fixed side plate 8 and the rotating side plate 9 is limited.

[0037] The drilling mechanism includes a vertically moving shell 28 mounted on the front surface of the housing 1 via a lifting mechanism. A drive motor 31 is fixedly mounted on the upper surface of the vertically moving shell 28 to provide power input for drilling. Three drive shafts 32 are rotatably mounted on the inner side of the vertically moving shell 28. Transmission gears 33 are fixedly mounted on the outer surface of the drive shafts 32 and the output shaft end of the drive motor 31, respectively. The drive shafts 32 and the output shaft of the drive motor 31 are connected by the transmission gears 33 to ensure smooth power distribution. Three connecting brackets 35 are fixedly connected to the lower end of the vertically moving shell 28. A drill bit 36 ​​is rotatably embedded in the inner side of each connecting bracket 35. The upper end of each drill bit 36 ​​is connected to the lower end of the drive shaft 32 via a universal transmission rod 34. The universal transmission rod 34 is a mechanical transmission component that connects two or more shafts with axial angles and relative position changes. It is existing technology and will not be described in detail.

[0038] The lifting mechanism includes a vertical cylinder 30 fixedly installed at the bottom of the housing 1. A lifting plate 29 is fixedly connected to the telescopic end of the vertical cylinder 30. The lifting plate 29 slides vertically with the housing 1, and the front end of the lifting plate 29 is fixedly connected to the vertical moving shell 28. The vertical cylinder 30 is hydraulically driven, outputting a stable vertical thrust to provide reliable power support for the lifting action of the vertical moving shell 28, driving the vertical moving shell 28 to move up and down as a whole, completing the feed adjustment and return reset of the drilling operation, and ensuring the coordination and accuracy of the mechanism's movement.

[0039] The telescopic mechanism includes a support frame 4 fixedly installed on the upper surface of the base 2. Transverse guide plates 6 are fixedly connected to both sides of the support frame 4. A movable plate 7 is slidably fitted on the outer surface of each side of the transverse guide plate 6. The transverse guide plate 6 serves as a guide and limiter. The movable plate 7 can slide smoothly along the transverse guide plate 6, effectively reducing movement deviation and shaking. The movable plates 7 on both sides are fixedly connected to the telescopic ends of the transverse cylinder 5. One end of the transverse cylinder 5 is fixedly connected to the side surface of the support frame 4. One side surface of the fixed side plate 8 is fixedly connected to the front end of the movable plate 7. A three-way seat 3 is fixedly installed on the upper surface of the base 2 near the front of the support frame 4. The three-way seat 3 provides bottom support for the motor housing 37. The protruding positions around the three-way seat 3 avoid the positions of the lower positioning block 12 and the clamping petals 11 to avoid scratching.

[0040] The locking mechanism includes a notch 16 at the front end of the fixed side plate 8. The rear end of the rotating side plate 9 is rotatably engaged with the inside of the notch 16. A rotating post 15 is fixedly inserted through the rear end of the rotating side plate 9, and the rotating post 15 rotatably passes through the inside of the notch 16, forming a rotatable hinged joint structure. A pressure plate 21 is threaded onto the upper end of the rotating post 15, and the pressure plate 21 presses against the upper surface of the fixed side plate 8. Lateral locking elements are respectively provided on the upper surfaces of the fixed side plate 8 and the rotating side plate 9. Rotating the pressure plate 21 presses it against the upper surface of the fixed side plate 8, achieving angular locking between the rotating side plate 9 and the fixed side plate 8.

[0041] The transverse locking component includes a sliding bar 17 slidably connected to the upper surfaces of the fixed side plate 8 and the rotating side plate 9, respectively. A slider 18 is fixedly connected to the lower surface of the sliding bar 17. Slide grooves 19 are respectively formed on the upper surfaces of the fixed side plate 8 and the rotating side plate 9. The slider 18 slides into the inner side of the slide groove 19, forming a stable transverse guiding fit, ensuring that the sliding bar 17 moves smoothly along a straight line without swaying. A return spring 20 is fixedly connected to the side of the slider 18 near the adjusting rod 10. The end of the return spring 20 is fixedly connected to the inner wall of the slide groove 19, providing a reliable return thrust for the sliding bar 17. A positioning gear 26 is fixedly sleeved on the outer surface of the adjusting rod 10. A toothed opening 25 is formed at one end of the sliding bar 17 near the adjusting rod 10, and the toothed opening 25 meshes with the positioning gear 26 to achieve reliable circumferential locking and positioning. An inclined guide surface 23 is formed at the other end of the sliding bar 17, facilitating a pushing fit with the pressure plate 21 during vertical movement.

[0042] The lower surface of the pressure plate 21 has a beveled edge 24, which pushes against the inclined guide surface 23 for smoother operation. The upper surface of the pressure plate 21 is fixedly connected to a polygonal block 22 for easy rotation by the user.

[0043] An anti-detachment ring 27 is fixedly sleeved on the outer surface of the adjusting rod 10. The anti-detachment ring 27 is rotatably embedded in the inner side of the fixed side plate 8 and the rotating side plate 9, thereby realizing the rotatable installation of the adjusting rod 10.

[0044] In use, the motor housing 37 is placed on the upper surface of the three-way seat 3. By controlling the retraction of the transverse cylinder 5, the two moving plates 7 on both sides are brought closer together, the adjusting rods 10 on both sides are brought closer together, and the positioning blocks 12 are clamped at the port of the motor housing 37. The two positioning blocks 12 at the front are located on both sides of the mounting lug 38, and the two positioning blocks 12 at the rear of one side are located in front of and behind the mounting lug 38 respectively. The lower connecting block 14 passes under the mounting lug 38 to achieve the technical effect of stabilizing the positioning of the motor housing 37, and avoids the mounting lug 38, motor heat sink and other positions, ensuring that the surface structure of the motor housing 37 will not be damaged during positioning.

[0045] During the positioning of the motor housing 37, the clamping flap 11 and the soft block 13 cover the area above the heat sink of the motor housing 37 around the mounting lug 38, effectively preventing metal debris from falling into the gap of the heat sink during drilling, which is beneficial for later cleaning and maintenance.

[0046] The user rotates the polygonal block 22 to move the pressure plate 21 upwards. Then, the angle between the fixed side plate 8 and the rotating side plate 9 can be adjusted, changing the distance between the two adjusting rods 10 on one side and the motor housing 37. This ensures that the clamping flap 11 can be close to the surface port of the motor housing 37. The adjusting rods 10 can rotate relative to the fixed side plate 8 and the rotating side plate 9, causing the positioning block 12 and the clamping flap 11 to rotate. This ensures that when the positioning block 12 is positioned on the surface of the motor housing 37, the clamping flap 11 can be as close as possible to the surface of the motor housing 37, allowing the soft block 13 to adhere tightly to the surface of the motor housing 37. This ensures the soft block 13's function of covering debris and the positioning block 12's clamping and positioning function. The state after positioning is as follows: Figure 10 , Figure 11 As shown. After the adjustment is completed, by rotating the polygonal block 22, the pressure plate 21 moves down, pushing the inclined guide surface 23 to move the sliding bar 17. The slider 18 slides along the inner side of the slide groove 19, squeezing the reset spring 20. After the toothed mouth 25 meshes with the surface of the positioning gear 26, the rotation angle of the adjusting rod 10 is fixed. At the same time, due to the tightening effect, the pressure plate 21 will also press against the upper surface of the fixed side plate 8, achieving the effect of locking the fixed side plate 8 and the rotating side plate 9. One rotation can complete the positioning of the angles of the two adjusting rods 10 and the angle between the fixed side plate 8 and the rotating side plate 9.

[0047] Driven by the motor 31, the power is transmitted through the transmission gear 33 to the drill bit 36 ​​via the transmission shaft 32 and the universal transmission rod 34, causing the drill bit 36 ​​to rotate and controlling the vertical cylinder 30 to retract, causing the lifting plate 29 and the vertical moving shell 28 to move down, and the drill bit 36 ​​to move down, drilling a hole in the surface where the lug 38 is installed.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
