Description

Technical Field

[0001] This application belongs to the field of motor manufacturing technology, and in particular relates to a drilling device for a motor housing base. Background Technology

[0002] like Figure 5 As shown, the motor housing 5 and its base 51 are generally formed as a single piece by casting. The casting mold forms mounting holes at the front and rear ends of the base 51. By installing connectors through the mounting holes, the motor can be stabilized on the frame or base of the equipment, ensuring that the motor will not shift during operation. However, according to the actual installation requirements of the motor, and in order to save on mold opening costs, a set of mounting holes needs to be drilled on the formed base 51 using a drilling device. However, general drilling devices have problems such as difficulty in loading and unloading the motor housing and incomplete motor positioning, resulting in low drilling efficiency and a high defect rate of the motor housing.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of the embodiments of this utility model clearer, the implementation methods of this utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this utility model are only some embodiments of this utility model, and not all embodiments.

[0024] Example 1

[0025] This application provides a drilling device for a motor housing base, such as... Figures 1-6 As shown, it includes: drilling mechanism 1, base 2, feeding mechanism 3, and fixing mechanism 4.

[0026] The base 2 is horizontally positioned. The drilling mechanism 1 includes a drill bit 11 vertically mounted on the base 2 and movable in the vertical direction. The drilling mechanism 1 also includes a drive unit 12 mounted on the base 2, which drives the drill bit 11 to rotate around its own axis and move in the vertical direction. The feeding mechanism 3 includes a slide rail 31 inclined on the base 2, with the higher end of the slide rail 31 located below the drill bit 11. A mounting platform 32 is slidably fitted on the slide rail 31 along its length, which is used to horizontally mount the motor housing 5 and restrict the horizontal movement of the motor housing 5. The fixing mechanism 4 includes a limiting plate 41 horizontally positioned between the drill bit 11 and the higher end of the slide rail 31, and a locking unit 42 acting on the mounting platform 32. The limiting plate 41 has a through hole 411 for the drill bit 11 to pass through. The limiting plate 41 and the locking unit 42 are used to fix the motor housing 5.

[0027] When applying, such as Figures 2-6As shown, the mounting platform 32 is slid along the length of the slide rail 31 to the outside of the limiting plate 41, and the motor housing 5 is horizontally installed onto the mounting platform 32, while keeping the base 51 facing upwards; the operator pushes the mounting platform 32 along the slide rail 31 toward the limiting plate 41. Because the limiting plate 41 is horizontally set, the motor housing 5 remains horizontal, and the base 51 remains facing upwards, so that when the mounting platform 32 is pushed up to a predetermined height along the slide rail 31, the bottom surface of the base 51 will be against the bottom surface of the limiting plate 41; the operator pushes the mounting platform 32, making the bottom surface of the base 51 press tightly against the bottom surface of the limiting plate 41, while the locking unit 42 fixes the position of the mounting platform 32; installation. Mounting platform 32 restricts the horizontal displacement of motor housing 5, while limiting plate 41 restricts the vertical displacement of motor housing 5. Simultaneously, limiting plate 41 cooperates with base 51 to restrict the rotation of motor housing 5, thereby effectively fixing motor housing 5 and its base 51. Drill bit 11 rotates and descends vertically under the drive of drive unit 12, drilling a hole in base 51 through through hole 411 on limiting plate 41. After drilling is completed, locking unit 42 releases mounting platform 32. Due to the gravity of mounting platform 32 and motor housing 5, mounting platform 32 will slide along slide rail 31 out below limiting plate 41, and then the drilled motor housing 5 can be removed. With the setting of the limiting plate 41 and the mounting platform 32, and in conjunction with the locking unit 42, the motor housing 5 and its base 51 can be effectively fixed, which effectively solves the problem of high drilling failure rate caused by the motor housing 5 not being fully limited; at the same time, with the cooperation of the mounting platform 32 and the slide rail 31, the loading and unloading process of the motor housing 5 is simplified, and the drilling efficiency of the motor housing 5 is greatly improved.

[0028] Specifically, such as Figures 3-5 As shown, there is a pair of slide rails 31 located on both sides of the mounting platform 32. A guide groove 311 is provided on the opposite side of each slide rail 31 along its length. The mounting platform 32 is horizontally positioned, and multiple pulleys 321 are arranged in an array on both sides along the length of the slide rails 31. The pulleys 321 slide within the guide grooves 311. Correspondingly, the guide grooves 311 can be T-slots or other structures that can cooperate with the pulleys 321. The motor housing 5 is generally made of iron or aluminum and has a certain weight, making it unsuitable for direct manual loading and unloading. However, through the cooperation of the pulleys 321 and the guide grooves 311, the slide rails 31 can bear part of the weight of the motor housing 5. This allows the operator to complete loading simply by providing a pushing force to move the mounting platform 32. During unloading, the mounting platform 32 automatically slides out under the weight of the motor housing 5, completing the unloading process. This significantly improves the drilling efficiency and ease of use of the drilling device.

[0029] Specifically, such as Figure 1 and Figure 2As shown, a placement groove 322 is horizontally formed on the top surface of the mounting platform 32. The placement groove 322 extends through one side of the mounting platform 32 and is a V-shaped groove. The length of the placement groove 322 is adapted to the length of the motor housing 5. A limiting block 323 is provided on one side of the mounting platform 32. When the motor housing 5 is inverted and placed horizontally in the placement groove 322, the limiting block 323 blocks one end of the motor housing 5 to restrict the horizontal movement of the motor housing 5. When the mounting platform 32 rises and the base 51 contacts the limiting plate 41, the V-shaped groove of the placement groove 322 allows the motor housing 5 to rotate around its own central axis, thereby causing the bottom surface of the base 51 to adaptively adhere to the bottom surface of the limiting plate 41, further simplifying the loading process of the motor housing 5.

[0030] Example 2

[0031] This embodiment is a further implementation of Embodiment 1 described above, such as... Figures 3-6 As shown, a pair of parallel support plates 21 are vertically mounted on the base 2, with the support plates 21 located on both sides of the mounting platform 32. A limiting plate 41 is located on the upper end of the support plates 21. The locking unit 42 includes a rotating shaft 43 horizontally mounted between the two support plates 21 and rotating about its own axis. Both ends of the rotating shaft 43 are rotatably fitted onto the corresponding support plates 21. A ratchet 44 is coaxially mounted on the rotating shaft 43. A mating shaft 45 is also mounted between the two support plates 21, rotating about its own axis and parallel to one side of the rotating shaft 43. One end of the mating shaft 45 is rotatably fitted onto the support plate 21. The other end of the mating shaft 45 passes through another support plate 21 and is connected to a rotating rod 451; a rocker arm 46 is vertically provided on the mating shaft 45, and one end of the rocker arm 46 forms a stop pawl 47 adapted to the tooth groove of the ratchet 44; an elastic element 48 is provided at the other end of the mating shaft 45, which can be a torsion spring. The torsion spring is sleeved on the other end of the mating shaft 45 and acts on the rotating rod 451 and the other support plate 21. The elastic element 48 is used to keep the stop pawl 47 in constant contact with the ratchet 44; a rack 49 is provided at the bottom of the mounting platform 32 along the length of the slide rail 31. The rack 49 is used to mesh with the ratchet 44.

[0032] In application, the elastic element 48 keeps the stop pawl 47 in constant contact with the ratchet 44. When the mounting platform 32 containing the motor housing 5 is pushed up along the slide rail 31 and is pushed close to the bottom surface of the limit plate 41, the rack 49 at the bottom of the mounting platform 32 begins to engage with the ratchet 44. At this time, the rotation direction of the ratchet 44 is the same as the orientation of the stop pawl 47. During the engagement of the rack 49 and the ratchet 44, the stop pawl 47 will move on the tooth surface of the ratchet 44 until it reaches the bottom surface of the base 51. The operator releases the mounting platform 32, which is tightly attached to the bottom surface of the limiting plate 41. Due to its own weight and the weight of the motor housing 5, the mounting platform 32 tends to slide down the slide rail 31. However, at this time, the ratchet 44 is already inserted into the tooth groove of the ratchet 44 under the action of the elastic element 48, thus fixing the mounting platform 32 and fixing the motor housing 5 and its base 51. When it is necessary to unload the material, simply rotate the rotating rod 451 to pull the stop pawl 47 out of the tooth groove of the ratchet 44. By setting the ratchet 44 and the stop pawl 47, and cooperating with the meshing of the rack 49 and the ratchet 44, the fixing method of the mounting platform 32 is simplified, and the convenience of the drilling device is further improved.

[0033] Specifically, such as Figures 3-5 As shown, there are two ratchet 44s, two rocker arms 46s, and two racks 49s. The ratchet 44s are set at a predetermined distance apart. The stop pawl 47 at one end of the rocker arm 46 engages with the corresponding ratchet 44. The rack 49 is located on both sides of the bottom of the mounting platform 32 and engages with the corresponding ratchet 44s. The engagement of the two sets of ratchet 44s and the stop pawl 47 can effectively improve the stability of the mounting platform 32.

[0034] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
