Description

Technical Field

[0001] This utility model relates to the field of motor housing processing technology, specifically to an opening tool for processing micro motor housings. Background Technology

[0002] The casing of a micro motor needs to be drilled near the shaft end face, with the holes evenly distributed in a ring shape. Current methods involve fixing the motor casing with a clamp and then drilling holes in the end face using the motor itself. This can be achieved by shifting the motor casing to drill holes in multiple locations. However, this current method of shifting and drilling the motor casing is cumbersome, and the precision and angle of the drilling position are difficult to control, leading to potential drilling position deviations. Furthermore, when drilling micro motors of different sizes, the position of the motor casing needs to be constantly adjusted, requiring multiple adjustments. This is not only cumbersome but also lacks adaptability, thus affecting drilling efficiency.

[0003] An existing patent (publication number: CN218532880U) discloses an opening tooling for processing micro motor housings, relating to the field of motor housing processing technology. This utility model includes a base plate, a support frame and a lifting column fixed to the top of the base plate, a drilling machine fixed to the top of the support frame, a support plate fixed to the top of the lifting column, a turntable rotatably connected to the top of the support plate, a motor fixed to the center of the bottom of the support plate, the motor's output shaft penetrating the support plate and fixedly connected to the turntable, and several clamping structures slidably connected to the outer circumference of the turntable.

[0004] Although this application can indicate the position of the drill bit on the micro motor housing at all times during drilling, facilitating the determination of the drilling position during processing and eliminating the need for frequent adjustments after bringing the drill bit close to the motor housing, thus simplifying the drilling positioning steps and improving positioning accuracy, this application cannot adjust the angle of the micro motor housing. When processing holes that are not horizontal or vertical, the operation becomes extremely cumbersome, requiring repeated disassembly and re-clamping of the workpiece. This not only seriously affects production efficiency but also easily introduces errors due to repeated positioning, leading to a decrease in hole position accuracy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hole-opening fixture for machining micro motor housings, which solves the problem that the angle of the micro motor housing cannot be adjusted, making the operation extremely cumbersome when machining holes in non-horizontal or non-vertical directions, requiring repeated disassembly and re-clamping of the workpiece.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tooling for machining the housing of a micro motor, comprising a base and an adjustment assembly mounted on the base, wherein a fixing assembly is mounted on the adjustment assembly, and an irregularly shaped clamping unit is provided on the surface of the fixing assembly, and the fixing assembly is movably mounted on the base via the adjustment assembly.

[0007] The adjustment assembly includes a mounting plate movably disposed above the base, and the fixing assembly includes a placement plate disposed above the base. A rotating rod is rotatably connected to the side of the mounting plate, and the other end of the rotating rod is fixed to the side of the placement plate. A connecting rod is fixed to the surface of the rotating rod, and a movable ball is fixed to the other end of the connecting rod. A movable plate is disposed above the base, and a movable groove is formed on the inner side of the movable plate. The movable ball is slidably engaged inside the movable groove.

[0008] Through the above scheme, the sliding of the movable ball in the moving groove, together with the linkage mechanism formed by the rotating rod and the connecting rod, enables the placement plate to achieve multi-angle tilt adjustment, thereby realizing the precise adjustment of the drilling angle of the motor housing, solving the problem of drilling in non-horizontal or non-vertical directions, eliminating the need for repeated disassembly of the workpiece, and improving processing efficiency and hole position accuracy.

[0009] Furthermore, an electric actuator is fixed to the upper surface of the base, and the output end of the electric actuator is fixed to the lower surface of the movable plate. The movable plate is movably mounted above the base via the electric actuator, and the placement plate is movably mounted above the base via the electric actuator, the movable plate, the movable ball, the connecting rod, and the rotating rod.

[0010] Through the above solution, the electric actuator provides precise linear drive. By controlling the lifting position of the moving plate, the tilt angle of the placement plate can be accurately controlled, realizing automated and digital control of angle adjustment and improving the accuracy and repeatability of angle adjustment.

[0011] Furthermore, a placement compartment is provided on the upper surface of the base, a rotary motor is fixed to the inner wall of the placement compartment, the output end of the rotary motor is fixed to the upper surface of the mounting plate, a slider is fixed to the lower surface of the mounting plate, a groove corresponding to the slider is provided on the upper surface of the base, the slider moves inside the groove, the mounting plate is movably set on the upper surface of the base through the rotary motor, the slider and the groove, the groove is annular, and there are two sliders, which are symmetrically arranged on the lower surface of the mounting plate.

[0012] The above scheme uses a rotary motor to drive the mounting plate to rotate. With the guidance of the annular groove and the slider, the circumferential position of the motor housing can be precisely adjusted. Furthermore, the symmetrical arrangement of the two sliders ensures the stability and balance of the rotation process, making the indexing operation during the machining of the annular hole more accurate and efficient.

[0013] Furthermore, the fixing assembly also includes a knob disposed on one side of the placement plate, a threaded rod fixed to the side of the knob, a transmission chamber opened inside the placement plate, the other end of the threaded rod being rotatably connected to the inner wall of the transmission chamber, a threaded cap being threadedly connected to the surface of the threaded rod, a connecting block being fixed to the upper surface of the threaded cap, and the upper surface of the connecting block being fixed to the lower surface of the irregular clamping unit.

[0014] Through the above scheme, the cooperation between the knob and the threaded rod enables the irregular clamping unit to move towards or away from each other, which can quickly adapt to motor housings of different sizes and provide uniform clamping force. Moreover, the motor housing can be fixed simply by turning the knob, making the operation simple, the clamping reliable, and effectively avoiding workpiece deformation and positioning deviation.

[0015] Furthermore, the upper surface of the placement plate is provided with a movable groove, which is connected to the transmission chamber. The upper end of the connecting block passes through the movable groove. The upper surface of the placement plate is also provided with a placement groove, which contains a collection box. Fixing bolts are provided on both sides of the placement plate, and the collection box is fixed inside the placement groove by the fixing bolts.

[0016] The above solution ensures that the movable slot moves smoothly for the irregularly shaped clamping unit. At the same time, the design of the collection box can effectively collect the debris generated during drilling, keeping the working environment clean. The fixing bolts ensure the stable installation of the collection box and facilitate disassembly and cleaning.

[0017] Furthermore, a cover plate is installed on the surface of the collection box, and multiple through holes are opened on the surface of the cover plate. The height of the collection box is flush with the upper surface of the placement plate, and the fixing bolt is located at the end away from the connecting rod.

[0018] The above solution allows the cover plate with through holes to effectively collect scattered debris, and the height of the cover plate being flush with the placement plate avoids interference with the placement and adjustment of the workpiece. The reasonable arrangement of the fixing bolts ensures the fixing effect while avoiding interference with the adjustment mechanism.

[0019] Furthermore, a lifting unit is installed on the upper surface of the base, and a drilling machine is installed on the lifting unit. The drilling machine is positioned above the fixed component, and the drilling machine is movably positioned above the fixed component via the lifting unit.

[0020] Through the above scheme, the lifting unit realizes the vertical feed motion of the drilling machine, which can accurately control the drilling depth and ensure the consistency of hole depth.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This drilling fixture for micro motor housing machining achieves precise multi-angle tilt adjustment of the placement plate by adjusting the electric actuator in the component to drive the moving plate to rise and fall. Combined with the sliding of the movable ball in the moving groove and the transmission of the rotating rod and connecting rod, this solves the problem of drilling in non-horizontal / vertical directions. A rotary motor drives the mounting plate to rotate within the annular slide groove, achieving precise indexing of the workpiece's circumferential position. Simultaneously, the knobs and threaded rods in the fixing component drive the movement of the irregularly shaped clamping unit, enabling rapid and stable clamping of motor housings of different sizes and shapes. This allows for precise machining of micro motor housings with multi-angle and multi-position drilling, improving processing efficiency, hole position accuracy, and equipment adaptability.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-5This embodiment provides a drilling fixture for processing micro motor housings, comprising a base 1 and an adjustment assembly 2 mounted on the base 1. A fixing assembly 3 is mounted on the adjustment assembly 2, and a shaped clamping unit 4 is provided on the surface of the fixing assembly 3. The fixing assembly 3 is movably positioned above the base 1 via the adjustment assembly 2. The moving plate 205 is raised and lowered by the electric push rod 207 in the adjustment assembly 2. With the sliding of the movable ball 204 in the moving groove 206 and the transmission of the rotating rod 202 and the connecting rod 203, the placement plate 301 can be precisely tilted at multiple angles, solving the problem of drilling in non-horizontal / vertical directions. The mounting plate 201 is rotated in the annular slide groove 102 by the rotary motor 208, achieving precise indexing of the circumferential position of the workpiece. At the same time, the shaped clamping unit 4 is moved by the knob 303 and the threaded rod 304 in the fixing assembly 3, achieving rapid and stable clamping of motor housings of different sizes and shapes. This enables precise processing of micro motor housings with multi-angle and multi-position drilling, improving processing efficiency, hole position accuracy, and equipment adaptability.

[0026] The adjustment component 2 includes a mounting plate 201 movably mounted above the base 1, and the fixing component 3 includes a placement plate 301 mounted above the base 1. A rotating rod 202 is rotatably connected to the side of the mounting plate 201, and the other end of the rotating rod 202 is fixed to the side of the placement plate 301.

The placement plate 301 is movably mounted above the base 1 via the electric actuator 207, the movable plate 205, the movable ball 204, the connecting rod 203, and the rotating rod 202. The electric actuator 207 provides precise linear drive. By controlling the lifting position of the movable plate 205, the tilt angle of the placement plate 301 can be accurately controlled, realizing automated and digital control of angle adjustment, and improving the accuracy and repeatability of angle adjustment. A placement chamber 101 is opened on the upper surface of the base 1. A rotary motor 208 is fixed to the inner wall of the placement chamber 101. The output end of the rotary motor 208... A slider 209 is fixed to the lower surface of the mounting plate 201 and fixed to the upper surface of the mounting plate 201. A groove 102 corresponding to the slider 209 is opened on the upper surface of the base 1. The slider 209 moves inside the groove 102. The mounting plate 201 is movably set on the upper surface of the base 1 by a rotary motor 208, the slider 209 and the groove 102. The groove 102 is annular. There are two sliders 209, which are symmetrically arranged on the lower surface of the mounting plate 201. The rotary motor 208 drives the mounting plate 201 to rotate. With the guiding effect of the annular groove 102 and the slider 209, the precise adjustment of the circumferential position of the motor housing is realized. In addition, the symmetrical arrangement of the two sliders 209 ensures the stability and balance of the rotation process, making the indexing operation during the machining of the annular hole more accurate and efficient.

[0028] The fixing assembly 3 also includes a knob 303 located on one side of the placement plate 301. A threaded rod 304 is fixed to the side of the knob 303.

A threaded cap 305 is threadedly connected to the surface of the threaded rod 304. A connecting block 306 is fixed to the upper surface of the threaded cap 305. The upper surface of the connecting block 306 is fixed to the lower surface of the irregular clamping unit 4. The cooperation of the knob 303 and the threaded rod 304 enables the irregular clamping unit 4 to move towards or away from each other, which can quickly adapt to motor housings of different sizes and provide uniform clamping force. Moreover, the motor housing can be fixed simply by turning the knob 303, making the operation simple and the clamping force convenient. Reliable and effectively avoids workpiece deformation and positioning deviation; the upper surface of the placement plate 301 is provided with a movable groove 307, which is connected to the transmission chamber 302. The upper end of the connecting block 306 passes through the movable groove 307. The upper surface of the placement plate 301 is also provided with a placement groove 308, and a collection box 5 is provided inside the placement groove 308. Fixing bolts 309 are provided on both sides of the placement plate 301. The collection box 5 is fixed inside the placement groove 308 by the fixing bolts 309. The movable groove 307 ensures that the irregular clamping unit 4 moves smoothly. At the same time, the design of the collection box 5 can effectively collect the debris generated during the drilling process, keep the working environment clean, and the fixing bolts 309 ensure the stable installation of the collection box 5 and facilitate disassembly and cleaning.

[0029] The collection box 5 is fitted with a cover plate, and the cover plate has multiple through holes. The height of the collection box 5 is flush with the upper surface of the placement plate 301. The fixing bolts 309 are located at the end away from the connecting rod 203. The cover plate with through holes can effectively collect scattered debris. The height of the collection box 5 being flush with the placement plate 301 avoids interference with the placement and adjustment of the workpiece. The reasonable arrangement of the fixing bolts 309 ensures the fixing effect and avoids interference with the adjustment mechanism.

[0030] It should be noted that a lifting unit 6 is installed on the upper surface of the base 1, and a drilling machine 7 is installed on the lifting unit 6. The drilling machine 7 is positioned above the fixed component 3, and the drilling machine 7 is movably positioned above the fixed component 3 through the lifting unit 6. The lifting unit 6 realizes the vertical feed movement of the drilling machine 7, which can accurately control the drilling depth and ensure the consistency of the hole depth.

[0031] The working principle of the above embodiments is as follows: First, the device is placed in the designated location. Then, it is connected to an external power source and control equipment. The control equipment specifically includes known conventional equipment such as a controller or computer with control functions. Next, the operator places the motor housing on the placement plate 301. Then, the operator turns the knob 303, which rotates the threaded rod 304. The threaded rod 304 moves the threaded cap 305, which in turn moves the connecting block 306 fixed on the upper surface of the threaded cap 305 and the irregular clamping unit 4 fixed on the upper end of the connecting block 306. This allows the irregular clamping unit 4 to fix the motor housing. Then, the operator controls the drilling machine 7 and the lifting unit 6 through the control equipment to drill holes in the fixed motor housing. The irregular clamping unit 4 on one side can be pre-adjusted or used as a fixed reference surface. When the motor housing is close to this reference surface, simply turning the knob 303 to move the clamping unit on the other side completes the clamping. This ensures that the workpiece has a fixed positioning reference every time it is clamped, improving the repeatability of the positioning accuracy.

[0032] When the angle of the motor housing needs to be adjusted, the operator controls the electric actuator 207 through the control equipment. The electric actuator 207 drives the moving plate 205 to move vertically, thereby moving the movable ball 204 inside the moving groove 206. The movable ball 204 drives the connecting rod 203 and the rotating rod 202 to rotate, which in turn drives the placement plate 301 and the motor housing fixed on the surface of the placement plate 301 to rotate. At the same time, the operator controls the rotary motor 208 through the control equipment. The rotary motor 208 drives the mounting plate 201 to rotate, thereby driving the motor housing to rotate, so that the drilling machine 7 can perform drilling operations at different positions of the motor housing.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
