Description

Technical Field

[0001] This utility model belongs to the field of motor processing technology and relates to a three-sided synchronous drilling and tapping mechanism for motor housing mounting holes. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. The motor housing is an important assembly component of the motor, serving to protect and install the stator shaft. The motor housing has four mounting holes for connecting to the motor mount. These four holes correspond to three sides of the motor housing. The existing technology for processing mounting holes is similar to a drilling and tapping device for housing processing disclosed in patent application number CN202221125194.4. This device sets up a worktable, fixed seats, and a drive mechanism, placing the drilling and tapping parts in the same device. The drive mechanism drives the four fixed seats on the worktable to rotate 90° each time, allowing the drilling and tapping parts to drill and tap the housing sequentially. During the processing, workers cooperate to remove the processed housing and fix the housing to be processed. The entire process is carried out in an orderly manner, greatly improving processing efficiency.

[0003] This processing method can only process one hole on one side at a time, requiring four cycles to ensure completion. Furthermore, processing with the same drill bit will affect the accuracy of the next hole, and the efficiency is not improved much. At the same time, the processing accuracy and quality cannot be guaranteed. Based on this, we designed a three-sided synchronous drilling and tapping mechanism for motor housing mounting holes. Summary of the Invention

[0004] The purpose of this invention is to provide a three-sided synchronous drilling mechanism for motor housing mounting holes to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a three-sided synchronous drilling and tapping mechanism for motor housing mounting holes, comprising a drilling frame and a machine tool protective cover. The machine tool protective cover is mounted on the top of the drilling frame, with the top edge of the drilling frame flush with the bottom edge of the machine tool protective cover. A four-position motor base is provided on one side of the top of the drilling frame, a cutter shaft clamping seat is provided on one side of the four-position motor base, a cutter shaft adjusting plate is provided on one side of the cutter shaft clamping seat, and four cutter head connectors are provided at one end of the cutter shaft adjusting plate. Drilling and tapping cutters are clamped and installed at one end of each of the four cutter head connectors. The four-position motor base is internally installed with... There are four servo motors, which are respectively bonded to four tool head connectors; a track groove is opened on the side of the top of the drilling frame, and a tilting motor frame is installed inside the track groove. A tilting motor is installed inside the tilting motor frame. The output end of the tilting motor is connected to a housing fixture seat through a coupling section. Four processing channels are opened at the horizontal seat of the housing fixture seat, and each processing channel corresponds to a drilling and tapping tool head. A housing limiting column is installed at the top of the horizontal seat of the housing fixture seat. A clamping seat limiting head is installed at the top of the housing limiting column. Two clamping blocks are installed at the top of the clamping seat limiting head.

[0006] In the aforementioned three-sided synchronous drilling mechanism for the motor housing mounting hole, a ball joint is installed on the side of the housing limiting column. One end of the ball joint is fitted with an abutment rod, and one end of the abutment rod is fitted with an abutment block. The abutment rod rotates relative to the housing limiting column via the ball joint, with the rotation angle not exceeding 35°. This design allows the abutment rod to be extended at a certain angle during motor housing installation, forming an acute angle with the housing limiting column. The abutment block contacts the inner wall of the motor housing, increasing the fastening force between the motor housing and the housing limiting column, thereby ensuring installation stability and reducing shaking during drilling.

[0007] In the aforementioned three-sided synchronous drilling mechanism for the motor housing mounting holes, a waste material discharge channel corresponding to the cutter shaft clamping seat is provided at the top of the drilling frame. This waste material discharge channel corresponds to the collection box inside the drilling frame. The purpose of this design is to allow the waste material generated during drilling to fall into the collection box inside the drilling frame under gravity, facilitating unified collection and enabling rapid cleaning, thus ensuring the drilling frame remains clean and tidy.

[0008] In the above-mentioned three-sided synchronous drilling and tapping mechanism for the motor housing mounting hole, a wedge-shaped clasp is provided at the top of the cutter shaft clamping seat, a Z-shaped rod is engaged at the wedge-shaped opening of the wedge-shaped clasp, a carbon plate mounting bracket is provided at the bottom of the Z-shaped rod, and a double-layer activated carbon plate corresponding to the drilling and tapping cutter head is installed inside the carbon plate mounting bracket.

[0009] Specifically, the vertical height between the two Z-shaped rods is greater than the height of the clamping seat limiting head, and the shortest distance between the Z-shaped rod and the top of the drilling machine frame is greater than the length of the housing limiting column. This design aims to use double-layer activated carbon plates to adsorb and treat the odorous gases generated during drilling, thereby reducing the amount of emitted odorous gases and mitigating environmental pollution in the workshop to some extent.

[0010] Compared with the prior art, the advantages of the three-sided synchronous drilling and tapping mechanism for motor housing mounting holes of this utility model are as follows: a four-station motor base is set on the top of the drilling frame, and four cutter head connectors are set at one end of the cutter shaft adjusting plate. Four servo motors are installed inside the four-station motor base, and each servo motor is respectively bonded to the corresponding cutter head connector. By opening four processing channels at the horizontal seat of the housing fixture, and each processing channel corresponding to a drilling and tapping cutter head, the four openings of the flipped motor housing can be aligned with the four drilling and tapping cutters, enabling synchronous drilling and tapping operations on the four holes, greatly ensuring the processing... Efficient and independent drilling and tapping head processing ensures the positional accuracy of each hole, guaranteeing machining accuracy and quality. By installing a ball joint on the side of the housing limiting column, with an abutment rod at one end and an abutment block at the other, the rotation angle of the abutment rod does not exceed 35°. This allows the motor housing to unfold the abutment rod at a certain angle during installation, forming an acute angle structure with the housing limiting column. The abutment block contacts the inner wall of the motor housing, increasing the fastening force between the motor housing and the housing limiting column, thereby ensuring the stability of the installation and reducing shaking during drilling and tapping.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model relates to a three-sided synchronous drilling and tapping mechanism for the motor housing mounting holes;

[0019] The main body of the mechanism includes a drilling machine frame 1 and a machine tool protective cover 2. The machine tool protective cover 2 is mounted on the top of the drilling machine frame 1 and the top edge of the drilling machine frame 1 is flush with the bottom edge of the machine tool protective cover 2.

[0020] To facilitate the clamping, loading, and unloading of the motor housing, the machine tool protective cover 2 is equipped with a sliding door. Figure 5 As shown, a controller, control computer, and keyboard (all common hardware devices in industrial machine tools in the prior art, equipped with corresponding software systems) are provided on the side of the machine tool protective cover 2, which facilitates PLC programming and can easily handle different opening sizes and better automated operation.

[0021] Example 1: A four-position motor base 3 is installed on one side of the top of the drilling machine frame 1. A cutter shaft clamping seat 4 is installed on one side of the four-position motor base 3. A cutter shaft adjusting plate 5 is installed on one side of the cutter shaft clamping seat 4. Four cutter head connectors 12 are installed at one end of the cutter shaft adjusting plate 5. Drilling and tapping cutters 13 are clamped and installed at one end of each of the four cutter head connectors 12. Four servo motors 11 are installed inside the four-position motor base 3. The four servo motors 11 are respectively keyed to the four cutter head connectors 12. A hole is opened on the side of the top of the drilling machine frame 1. The track groove 6 has a rotating motor frame 7 installed inside it. The rotating motor frame 7 has a rotating motor 18 installed inside it. The output end of the rotating motor 18 is connected to the housing fixture seat 8 via a coupling section. Four processing channels 21 are opened at the horizontal seat of the housing fixture seat 8, and each processing channel 21 corresponds to a drill bit 13. A housing limiting column 9 is installed at the top of the horizontal seat of the housing fixture seat 8. A clamping limit head 19 is installed at the top of the housing limiting column 9. Two clamping blocks 20 are installed at the top of the clamping limit head 19.

[0022] In the above technical solution, when in use: the motor housing and housing limiting column 9 are fitted together and contact the housing clamp seat 8. The two clamping blocks 20 are adjusted to press the upper end of the motor housing. Since the side of the housing limiting column 9 is equipped with a ball head 23, and one end of the ball head 23 is equipped with an abutting rod 22, the abutting rod 22 rotates relative to the housing limiting column 9 through the ball head 23. The abutting block 24 of the abutting rod 22 contacts the inner wall of the motor housing, thereby improving the firmness of the motor housing installation.

[0023] In this design, the rotation angle of the contact rod 22 does not exceed 35°. The force required to flip the contact rod 22 upwards is smaller, and the force required to flip the contact rod 22 downwards is larger. The force reaches its maximum when the motor housing contacts the outer casing clamp seat 8, ensuring the stability of the installation.

[0024] In Embodiment 1, in order to facilitate the collection of waste chips, a waste chip discharge channel 10 corresponding to the cutter shaft clamping seat 4 is provided at the top of the drilling machine frame 1. The waste chip discharge channel 10 corresponds to the collection box inside the drilling machine frame 1.

[0025] Example 2: A wedge-shaped holder 14 is provided at the top of the cutter shaft clamping seat 4. A Z-shaped rod 15 is engaged at the wedge-shaped opening of the wedge-shaped holder 14. A carbon plate mounting bracket 16 is provided at the bottom of the Z-shaped rod 15. A double-layer activated carbon plate 17 corresponding to the drilling and tapping head 13 is installed inside the carbon plate mounting bracket 16. This solution uses the double-layer activated carbon plate 17 to adsorb and treat the odorous gas generated by drilling and tapping, which can reduce the amount of odorous gas emitted and reduce the environmental pollution of the workshop to a certain extent.

[0026] Furthermore, the vertical height between the two rods of the Z-shaped rod 15 is greater than the height of the clamping head 19, and the shortest distance between the Z-shaped rod 15 and the top of the drilling frame 1 is greater than the length of the housing limiting column 9. This ensures that the double-layer activated carbon plate 17 is located at the upper end of the entire motor housing processing position, without affecting the movement of the housing clamping seat 8 or hindering the machining of the motor housing. As the gas rises due to heating, it can achieve a certain adsorption effect, reducing the amount of odorous gas.

[0027] In use: Adjust the abutting rod 22 and the abutting block 24 so that the abutting rod 22 opens at a certain angle, and put the motor housing and housing limiting column 9 into contact with the housing clamp seat 8. Adjust the two clamping blocks 20 to press down the upper end of the motor housing. By flipping the motor 18, the motor housing is flipped. The flipping motor frame 7 slides along the track groove 6 to the part of the tool shaft clamping seat 4, so that each processing channel 21 corresponds to a drilling and tapping head 13. After simple tool setting, the drilling and tapping head 13 corresponds to the opening position of the motor housing. The four servo motors 11 are driven synchronously, which can simultaneously drill and tap the four holes, greatly ensuring processing efficiency. The independent drilling and tapping head 13 ensures the positional accuracy of each hole, so that the processing accuracy and processing quality are guaranteed.

[0028] In this design, the drill-tapping head 13 is divided into a drill bit and a tapping head, which perform drilling and tapping operations simultaneously, requiring tool changes during the process. Since tool changing is a common machining operation, it will not be described again here.
