Description

Technical Field

[0001] This utility model belongs to the field of motor assembly technology, and in particular relates to a tool table for assembling motor stators. Background Technology

[0002] DD direct drive motors, also known as direct drive motors, are sometimes referred to as torque servos by some companies due to their large output torque. Unlike traditional motors, their high torque allows them to be directly connected to motion devices, eliminating the need for connecting mechanisms such as gearboxes and belts, hence the name direct drive motor.

[0003] The existing direct drive motors rely on manual assembly of the moving and stating components, which results in inaccurate positioning, low efficiency, and difficulty in limiting and fixing motor stators of different sizes.

[0004] According to the public announcement (CN221828767U), a general-purpose DD motor stator assembly tooling is disclosed. This technology discloses "a technical solution including a work platform on which the DD motor stator is mounted; a flange bearing mounted on the work platform, etc., which has the technical effect of facilitating the installation of the mover inside the stator."

[0005] In this existing design, the stator of the DD motor is mounted on the work platform of the tooling. However, since the existing direct drive motor uses manual operation when assembling the moving stator, there are problems such as inaccurate positioning and low efficiency, and it is not convenient to limit and fix motor stators of different sizes.

[0006] Therefore, we need to design a tool table for assembling motor stators to solve these problems. Utility Model Content

[0007] The problem to be solved by this utility model is to provide a tool table for assembling motor stators.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A tool table for assembling a motor stator includes a frame, a pressing assembly mounted on the frame, and a fixed platform located inside the frame below the pressing assembly. The pressing assembly reciprocates horizontally above the fixed platform. The pressing assembly includes a slide connected to the frame via a traveling mechanism. A pressing cylinder is fixedly mounted on the slide, and a pressing mold is fixedly mounted at the output end of the cylinder, located above the fixed platform. The fixed platform includes a support block and a clamping drive mechanism, both connected to the frame. A support plate is mounted on the support block, and two sliding frames are mounted on the support plate. Each sliding frame has a clamping block, and the clamping drive mechanism is connected to the sliding frame.

[0010] Preferably, the fuselage frame includes a base plate and two support frames, the two support frames are fixed on the base plate, the fixed platform is disposed on the base plate between the two support frames, and the walking mechanism is fixedly disposed on the top of the two support frames.

[0011] With this configuration, the fuselage frame adopts a portal structure of "base plate + support frame". The base plate provides stable foundation support, and the two support frames are vertically fixed to the base plate to form a rigid frame that can withstand the vertical load and horizontal movement load during the pressing process.

[0012] The fixed platform is set on the base plate between the support frames. The support force of the base plate is used to prevent the fixed platform from deforming due to the pressing force. The traveling mechanism is installed on the top of the support frame, which distributes the weight and motion load of the pressing components to the support frames on both sides, improving the stability and anti-overturning ability of the overall structure. At the same time, the top installation method leaves enough operating space under the fixed platform.

[0013] Preferably, the walking mechanism includes a connecting block, a mounting plate, a walking motor, a walking gear, and a rack. The rack is fixed to the top of the machine frame, the mounting plate is fixed to the bottom of the slide via the connecting block, the walking motor is fixedly mounted on the mounting plate, and the walking gear at the output end of the walking motor is fixed and meshes with the rack.

[0014] This configuration, employing a "motor + gear and rack" transmission structure, features high transmission efficiency and stable motion accuracy. The traveling motor directly drives the gear and rack, enabling linear reciprocating motion of the slide and avoiding slippage issues associated with flexible connections like belt drives, thus improving control precision. The controllable gear backlash, combined with precise motor speed control, allows for accurate adjustment of the pressing component's position and speed, meeting the positioning requirements of different pressing processes. Furthermore, the mounting plate is fixed to the bottom of the slide via connecting blocks, ensuring even load distribution to the slide and guaranteeing stability during movement, minimizing the impact of vibration on pressing accuracy.

[0015] Preferably, a limiting strip is fixedly provided on the top of the frame on one side of the rack, the limiting strip has an inverted L-shaped cross section, and a limiting wheel is rotatably provided on the mounting plate on one side of the traveling gear, and the limiting wheel cooperates with the limiting strip.

[0016] This design, with the matching limit bar and limit wheel, provides dual guidance and anti-derailment functions for the traveling mechanism. The inverted L-shaped limit bar is fixed to the top of the machine frame, and the limit wheel is mounted on the mounting plate and contacts the vertical surface of the limit bar. This limits the lateral displacement of the slide during horizontal movement, ensuring that the pressing assembly moves linearly along the rack direction. Simultaneously, the horizontal lip of the limit bar prevents the limit wheel from derailing, avoiding derailment of the traveling mechanism due to accidental impact or overload, thus improving the safety of equipment operation. The overall structure is simple and reliable, achieving mechanical limiting without complex sensors, reducing maintenance costs.

[0017] Preferably, the clamping drive mechanism includes a threaded rod and a clamping motor. The threaded rod is located below the support plate, and its two ends are rotatably connected to the support block. A driven pulley is fixedly fitted in the middle of the threaded rod. The threads on both sides of the driven pulley have opposite directions. The two sliding frames are respectively connected to the threaded rods on both sides of the driven pulley. The clamping motor is fixed on the machine frame, and a drive pulley is fixedly provided at the output end of the clamping motor. The drive pulley and the driven pulley are connected to each other through a transmission belt.

[0018] This configuration employs a "threaded rod + reverse thread" transmission design for the clamping drive mechanism. Driven by a clamping motor and pulleys, it enables synchronous reverse movement of the two sliding frames: the threads on both sides of the threaded rod have opposite directions. When the motor drives the threaded rod to rotate, the two sliding frames simultaneously move towards the center or to the sides, ensuring symmetrical clamping of the workpiece by the two clamping blocks and preventing workpiece deformation due to eccentric force. The belt drive structure has a buffering and vibration-absorbing effect, reducing impact during start-up and stopping. Simultaneously, the constant pulley transmission ratio ensures consistent clamping position. Furthermore, the rotatable connection of the threaded rod's two ends to the support blocks and its placement under the support plate saves space, making the fixed platform structure more compact.

[0019] Preferably, there are two threaded rods, which are symmetrically distributed along the clamping block.

[0020] This configuration, with two symmetrically distributed threaded rods, significantly improves the stability of the clamping mechanism and the uniformity of the clamping force. Each threaded rod corresponds to a set of sliding frames and clamping blocks. The symmetrical layout ensures that the clamping force is evenly applied to both sides of the workpiece, avoiding force imbalance caused by single threaded rod transmission. The double threaded rod structure is equivalent to increasing transmission redundancy. Even if one threaded rod experiences slight wear or uneven force, the other threaded rod can still help maintain clamping accuracy and improve the reliability of the mechanism.

[0021] Preferably, the fixed platform further includes two slide rails and several sliders. The two slide rails are symmetrically distributed on the top of the tray along the clamping block, and the several sliders are slidably disposed on the slide rails. The number of sliders on the two slide rails is the same, and the sliding frame is fixedly connected to the sliders.

[0022] This design, with slide rails and sliders on the top of the pallet, provides low-friction, high-precision guiding support for the movement of the sliding frame. The slide rails are symmetrically distributed on both sides of the clamping block, and the sliders are fixedly connected to the sliding frame, ensuring that the sliding frame always moves linearly along the slide rails during movement, reducing jamming or misalignment caused by uneven friction. The small clearance between the slide rails and sliders ensures accurate positioning of the clamping block, thereby guaranteeing the positional accuracy of the workpiece during press-fitting. Furthermore, this structure uses standardized slide rail components for easy maintenance and replacement, and the number of sliders is designed according to the load of the sliding frame, evenly distributing the clamping force and preventing excessive localized stress and deformation of the pallet.

[0023] Preferably, the clamping block is provided with a positioning groove, the clamping blocks on the two sliding frames are positioned opposite each other, and the opening directions of the positioning grooves on the two clamping blocks are opposite to each other.

[0024] This configuration, with its positioning grooves and relative layout design on the clamping blocks, provides precise positioning and clamping for the workpiece. The shape of the positioning groove matches the workpiece, and the positioning grooves on both sides of the clamping blocks limit the workpiece's position, ensuring that the workpiece is fixed in both the horizontal and vertical directions, thus avoiding pressing deviations caused by workpiece skewing during pressing. The two clamping blocks are positioned opposite each other, and the openings of the positioning grooves are opposite to each other, which can form a symmetrical clamping force, evenly clamping the workpiece. This not only ensures clamping stability but also controls the workpiece's clamping position through the dimensional accuracy of the positioning grooves, improving the consistency of the pressing process.

[0025] Preferably, the pressing mold is provided with a plurality of waist-shaped holes, and the plurality of waist-shaped holes are evenly distributed radially around the pressing cylinder.

[0026] This design, with its radial waist-shaped holes, gives the press-fitting mold high installation flexibility and adjustability. The waist-shaped holes allow for adjustment of the installation position within a certain range. The radial layout centered on the press-fitting cylinder allows the mold to move radially, adapting to the press-fitting requirements of workpieces with different center distances or different sizes, thus improving the press-fitting quality.

[0027] The advantages and positive effects of this utility model are:

[0028] This utility model improves installation accuracy, reduces manual operation, increases installation efficiency, saves time and effort, and reduces safety risks during manual installation by using the press-fit components and the fixing platform. In addition, the adjustable fixing platform can fix motor stators of different sizes, and has a wide range of applications, which greatly improves assembly efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] Example 1: As Figures 1-7 As shown, a tool table for assembling a motor stator includes a machine frame 1, a pressing assembly 2 is provided on the machine frame 1, a fixed platform 3 is provided on the inner side of the machine frame 1 below the pressing assembly 2, and the pressing assembly 2 moves horizontally back and forth above the fixed platform 3.

[0043] The pressing assembly 2 includes a slide 21, which is connected to the machine frame 1 through a walking mechanism. A pressing cylinder 29 is fixedly installed on the slide 21, and a pressing mold 25 is fixedly installed at the output end of the pressing cylinder 29. The pressing mold 25 is located above the fixed platform 3.

[0044] The fixed platform 3 includes a support block 31 and a clamping drive mechanism. Both the clamping drive mechanism and the support block 31 are connected to the machine frame 1. The support block 31 is provided with a tray 32, and the tray 32 is provided with two sliding frames 35. Each sliding frame 35 is provided with a clamping block 36. The clamping drive mechanism is connected to the sliding frame 35.

[0045] When the traveling mechanism drives the slide 21 to move, the pressing cylinder 29 can move with the slide 21 above the fixed platform 3, while the clamping drive mechanism can control the movement of the clamping block 36 to clamp the workpiece on the fixed platform 3, so that the pressing mold 25 can accurately perform pressing operation on the workpiece.

[0046] The fuselage frame 1 includes a base plate 11 and two support frames 12. The two support frames 12 are fixed on the base plate 11. The fixed platform 3 is set on the base plate 11 between the two support frames 12. The walking mechanism is fixed on the top of the two support frames 12.

[0047] The base plate 11 provides a stable mounting foundation for the entire frame 1. Two support frames 12 are vertically fixed to the base plate 11, which not only provides an installation position for the traveling mechanism, but also forms a stable structure together with the base plate 11. The fixed platform 3 fixed on the base plate 11 can remain stable during the pressing process. The traveling mechanism installed on the top of the support frame 12 can drive the pressing assembly 2 to move above the fixed platform 3, thereby realizing the rational spatial layout of the pressing assembly 2 and the fixed platform 3.

[0048] The traveling mechanism includes a connecting block 22, a mounting plate 28, a traveling motor 20, a traveling gear 26, and a rack 27. The rack 27 is fixed to the top of the machine frame 1. The mounting plate 28 is fixed to the bottom of the slide plate 21 through the connecting block 22. The traveling motor 20 is fixedly mounted on the mounting plate 28. The traveling gear 26 at the output end of the traveling motor 20 is fixed and meshes with the rack 27.

[0049] When the walking motor 20 is working, it drives the walking gear 26 to rotate. Since the walking gear 26 meshes with the rack 27, it drives the mounting plate 28 and the slide plate 21 connected to it to move horizontally along the rack 27, realizing the horizontal reciprocating motion of the pressing assembly 2 above the fixed platform 3, so that the pressing mold 25 can be moved to different positions above the fixed platform 3 for pressing operations.

[0050] A limit bar 23 is also fixedly installed on the top of the frame 1 on one side of the rack 27. The cross-section of the limit bar 23 is inverted L-shaped. A limit wheel 24 is also rotatably installed on the mounting plate 28 on one side of the traveling gear 26, and the limit wheel 24 cooperates with the limit bar 23.

[0051] During the movement of the slide 21 driven by the traveling gear 26, the limiting wheel 24 rolls along the limiting strip 23. The inverted L-shaped structure of the limiting strip 23 can limit the movement range of the limiting wheel 24, prevent the slide 21 from shifting laterally during the movement, and ensure that the slide 21 moves smoothly along the rack 27 direction, so that the pressing mold 25 can be accurately aligned with the workpiece position on the fixed table 3 when it moves. At the same time, the horizontal lip of the limiting strip 23 can prevent the limiting wheel 24 from leaving the track.

[0052] The clamping drive mechanism includes a threaded rod 40 and a clamping motor 41. The threaded rod 40 is located below the support plate 32, and its two ends are rotatably connected to the support block 31. A driven pulley 30 is fixedly fitted in the middle of the threaded rod 40. The threads on both sides of the driven pulley 30 have opposite directions. Two sliding frames 35 are respectively connected to the threaded rods 40 on both sides of the driven pulley 30. The clamping motor 41 is fixed on the machine frame 1, and a drive pulley 42 is fixedly installed at the output end of the clamping motor 41. The drive pulley 42 and the driven pulley 30 are connected to each other through a transmission belt 39.

[0053] After the clamping motor 41 is started, it drives the pulley 42 to rotate, which in turn drives the driven pulley 30 and the threaded rod 40 to rotate via the transmission belt 39. Since the threads on both sides of the threaded rod 40 are opposite in direction, the two sliding frames 35 will move along the threaded rod 40 towards the center or to both sides, thereby driving the clamping block 36 to clamp or release the workpiece, thus fixing the workpiece on the fixed table 3 and preparing for the press-fitting operation.

[0054] There are two threaded rods 40, and the two threaded rods 40 are symmetrically distributed along the clamping block 36.

[0055] Two symmetrically distributed threaded rods 40 can simultaneously drive their corresponding sliding frames 35 to move, so that the two clamping blocks 36 move synchronously, ensuring that the clamping force on the workpiece is evenly distributed on both sides of the workpiece, avoiding the force imbalance caused by the transmission of a single threaded rod 40, enhancing the stability and reliability of the clamping mechanism, and keeping the workpiece stable during the clamping process.

[0056] The fixed platform 3 also includes two slide rails 33 and several sliders 34. The two slide rails 33 are symmetrically distributed on the top of the support plate 32 along the clamping block 36. Several sliders 34 are slidably arranged on the slide rails 33, and the number of sliders 34 on the two slide rails 33 is the same. The sliding frame 35 is fixedly connected to the sliders 34.

[0057] When the sliding frame 35 moves under the drive of the clamping drive mechanism, the sliding frame 35 slides on the slide rail 33 through the slider 34. The slide rail 33 provides guidance for the slider 34, making the movement of the sliding frame 35 more stable and precise, reducing friction and resistance during the sliding process, and ensuring that the clamping block 36 can move accurately to the predetermined position to achieve precise clamping of the workpiece.

[0058] The clamping block 36 is provided with a positioning groove 37. The clamping blocks 36 on the two sliding frames 35 are positioned opposite each other, and the opening directions of the positioning grooves 37 on the two clamping blocks 36 are opposite.

[0059] When the two clamping blocks 36 move toward the center under the action of the clamping drive mechanism, the corresponding positioning grooves 37 can position and clamp the workpiece. The shape of the positioning grooves 37 matches the workpiece, which can restrict the movement of the workpiece and keep the workpiece in an accurate position on the fixed table 3, ensuring that the pressing mold 25 can accurately act on the pressing part of the workpiece when it presses down.

[0060] The pressing mold 25 is provided with several waist-shaped holes 38, which are evenly distributed radially around the pressing cylinder 29.

[0061] The output end of the pressing cylinder 29 is connected to the pressing mold 25. The waist-shaped holes 38 radially distributed on the pressing mold 25 with the pressing cylinder 29 as the center can adjust the installation position of the motor rotor 6 on the pressing mold 25, adapt to the pressing requirements of workpieces of different sizes and center distances, ensure the centering accuracy, and enable the pressing force to be accurately transmitted to the workpiece.

[0062] The working process of this embodiment is as follows: In order to avoid shaking during the assembly of the motor stator 5 and the motor rotor 6, it is necessary to fix them first. Before fixing, the power of the walking motor 20 is turned on and the pressing assembly 2 is moved to one side. Then the power of the clamping motor 41 is turned on, so that the drive pulley 42 on the clamping motor 41 rotates. The two driven pulleys 30 are driven to rotate through the transmission belt 39. When the driven pulleys 30 rotate, they will drive the threaded rod 40 to rotate. After the threaded rod 40 rotates, it will drive the sliding frame 35 to move along the slide rail 33. When the two sliding frames 35 move away from each other, they will drive the two clamping blocks 36 to separate. At this time, the motor stator 5 is placed on the support plate 32 and the motor is started. The threaded rod 40 drives the two clamping blocks 36 to move relative to each other. The motor stator 5 is clamped through the positioning groove 37, thus completing the fixing of the motor stator 5.

[0063] Next, the bolts are passed through the oblong hole 38, and the motor rotor 6 is fixed onto the press mold 25. After it is fixed, the walking motor 20 will drive the motor rotor 6 to move above the electronic stator. Then the press cylinder 29 will extend and drive the motor rotor 6 downward through the press mold 25 to install the motor rotor 6 into the motor stator 5. Then the bolts fixing the motor rotor 6 are removed, and the clamping motor 41 drives the two lead screws to rotate again, causing the two clamping blocks 36 to separate. The assembled motor stator 5 is then removed from the support plate 32. The equipment is simple to operate, saves time and effort, is convenient for workers to use, and improves work efficiency.

[0064] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
