Description

A yaw meter workbench fixture for motor manufacturing Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a jig for a yaw meter workbench used in motor manufacturing. Background Technology

[0002] The compressor is one of the core components of an air conditioning system. Its main function is to achieve a cooling effect by compressing refrigerant gas. A traditional compressor typically consists of basic components such as a housing, stator, rotor, end caps, and liquid receiver.

[0003] In the processing of air conditioner compressor stators, the detection of stator expansion, concentricity, and perpendicularity is crucial for ensuring machining accuracy. Traditional detection methods typically rely on manual operation and multi-device collaboration. The process involves assembling the stator and expansion sleeve, placing it on the product piping structure, manually applying pressure to the conical shaft using a jack to expand the stator, and then using a runout gauge to check the stator's form and position tolerances. However, this technology has the following significant drawbacks:

[0004] 1. The operation process is cumbersome and inefficient: The testing process involves multiple manual handling operations (such as stator lifting, cone shaft pressurization, equipment reset, etc.), and each step relies on manual switching, resulting in a long testing cycle and making it difficult to meet the needs of large-scale production.

[0005] 2. Poor equipment coordination: The yaw meter lacks integrated control with the product pipeline mechanism, pressurization mechanism, etc., and the positioning reference needs to be repeatedly adjusted during reset, which leads to the accumulation of repeated positioning errors and reduces the consistency of detection.

[0006] Furthermore, in existing technologies, the runout gauge is typically used as an independent detection unit, separate from the worktable of the stator expansion process. This makes it difficult to correlate the detection data with the processing status in real time, hindering dynamic compensation. Therefore, there is an urgent need for an integrated control device to optimize the detection process, improve accuracy, and reduce manual intervention, thereby ensuring the processing quality and production efficiency of the compressor's core components. Summary of the Invention

[0007] This utility model is a jig for a yaw meter workbench used in motor manufacturing, designed to overcome the technical problems existing in the prior art.

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

[0009] A yaw rate tester worktable fixture for motor manufacturing includes: a worktable conveying mechanism, an axial pressing mechanism, a yaw rate detection mechanism, and a positioning clamp; the axial pressing mechanism and the yaw rate detection mechanism are disposed on the worktable, and the die-casting end of the axial pressing mechanism corresponds to the detection end of the yaw rate detection mechanism; the conveying mechanism is installed on the worktable below the axial pressing mechanism, and the conveying mechanism is used to hold the workpiece and transport it to the axial pressing mechanism and the yaw rate detection mechanism; the positioning clamp is disposed on the axial pressing mechanism to fix the axial movement of the workpiece.

[0010] Furthermore, the conveying mechanism includes a workpiece support platform, a lifting assembly, and a sliding table assembly; the workpiece support platform is installed above the lifting assembly; the sliding table assembly is movably disposed above the worktable and transports the workpiece within the workpiece support platform by sliding; the lifting assembly is installed on the worktable and connected below the sliding table assembly, and is used to drive the sliding table assembly to lift and lower.

[0011] Furthermore, the workpiece support platform is also connected to a handle, and the workpiece support platform is provided with a groove for holding the workpiece being processed.

[0012] Furthermore, the sliding table assembly includes a sliding table base, a movable frame, and a carriage;

[0013] The slide base is located above the worktable, the movable frame is slidably connected to the slide base, the bottom of the movable frame is connected to a lifting component to achieve vertical movement, and the workpiece support platform is connected to the slide frame via a slide rail.

[0014] Furthermore, the slide base is movably connected to the upper part of the slide base by bolts, and the lifting part of the lifting assembly abuts against the slide base to achieve vertical movement.

[0015] Furthermore, the axial pressing mechanism includes a conical shaft pressing mechanism, a conical shaft pressing mechanism, and an expansion assembly; the conical shaft pressing mechanism and the conical shaft pressing mechanism are axially aligned, and the conical shaft pressing mechanism is connected to the conical shaft pressing mechanism through the expansion assembly.

[0016] Furthermore, the expansion assembly is an expansion sleeve, with a pressure rod sleeved inside the expansion sleeve and a workpiece sleeved outside the expansion sleeve. Expansion is achieved by connecting the pressure rod to the conical shaft pressing mechanism.

[0017] Furthermore, the conveying mechanism is located below the conical shaft pressing mechanism and the conical shaft pressing mechanism, and transports the workpiece to the sway detection mechanism by sliding and lifting.

[0018] Furthermore, the yaw detection mechanism includes a yaw slide rail base and a yaw positioning frame; the yaw positioning frame is connected to the yaw slide rail base and can slide along the length of the yaw slide rail base.

[0019] Furthermore, the eccentric positioning frame is connected to a pressure bar via a transmission to achieve rotation detection of the workpiece.

[0020] Preferably, the movable frame is connected to the slide base by a movable bolt and can slide along the height direction of the slide base.

[0021] Preferably, the bottom of the second carriage and the workpiece support table are equipped with pneumatic or electric slide rails.

[0022] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0023] ① Improved operational efficiency and stability

[0024] Hydraulic and screw-feed technology replaces manual hammering. By employing a hydraulic ejection device and a screw-feed mechanism, it solves the problems of time-consuming and labor-intensive traditional manual hammering methods, significantly improving the efficiency of mandrel pressing (such as pressing in / out of the mandrel). Simultaneously, it ensures a smooth and stable pushing process, reduces human error, and enhances overall stability. The mandrel pressing mechanism uses a screw-feed, which employs a screw propulsion principle, ensuring a smooth and stable mandrel pushing process, greatly improving work efficiency (especially in mass production scenarios). It is also suitable for rapid switching between different machine specifications. The hydraulic ejection device is safer and more effective than mechanical mechanisms.

[0025] ② Multi-model compatibility

[0026] The mandrel uses a replaceable expansion sleeve structure (with a pressure rod), allowing it to be adapted to different motor stator products by simply replacing the expansion sleeve with different specifications, without having to replace the entire mandrel. This design significantly reduces the replacement cost of developing new models, shortens model changeover time (e.g., only the expansion sleeve needs to be replaced instead of the complex mandrel), improves the versatility of the fixture, and the addition of an expansion sleeve to the mandrel supporting the stator product makes installation easier in a free state. Furthermore, different models can be used with different expansion sleeves, eliminating the need to replace the entire mandrel; model changeover is quicker and more convenient; and the cost of replacing the expansion sleeve for new models in the future is relatively low.

[0027] ③ Improved detection efficiency

[0028] Traditional sway detection relies on manual handling of workpieces and adjustment of their position. However, this invention achieves automated workpiece transport and height adjustment through a sliding table base and lifting components, reducing the time spent on manual adjustments and significantly improving detection efficiency.

[0029] ④ Enhance workpiece fixation stability

[0030] The yaw positioning frame is connected to a pressure bar, which provides reliable support during rotational testing, enabling the workpiece to be tested in a stable state. This reduces errors in the yaw testing process, improves the repeatability and reliability of measurements, and ensures the accuracy of measurement results. Attached Figure Description

[0051] Example 1

[0052] As shown in Figures 1-11, this embodiment discloses a yaw tester workbench fixture for motor manufacturing, including: a workbench 1, a conveying mechanism 2, an axial pressing mechanism 3, a yaw detection mechanism 4, and a positioning clamping plate 5; the axial pressing mechanism 3 and the yaw detection mechanism 4 are disposed on the workbench 1, and the die-casting end of the axial pressing mechanism 3 corresponds to the detection end of the yaw detection mechanism 4; the conveying mechanism 2 is installed on the workbench 1 below the axial pressing mechanism 3, and the conveying mechanism 2 is used to hold the workpiece and transport it to the axial pressing mechanism 3 and the yaw detection mechanism 4; the positioning clamping plate 5 is disposed on the axial pressing mechanism 3 to fix the axial movement of the workpiece.

[0053] During operation, the operator places the stator workpiece with the expansion sleeve inside into the workpiece support table 201 (groove) and adjusts its position using the handle to ensure stability.

[0054] Then, the lifting assembly 202 drives the sliding table assembly 203 (including the sliding table base 2031, the movable frame 2032, and the slide 2033) to rise, so that the workpiece is transported to the stamping end of the axial pressing mechanism 3; the conical shaft is manually sent into the expansion sleeve, and the pressure bar is placed on the axial pressing mechanism 3. Then, the handwheel of the screw jack is turned so that the axial pressing mechanism 3 impacts the pressure bar to press the conical shaft until the conical shaft of the pressure bar is pressed tightly into the expansion sleeve;

[0055] Then, the jack is retrieved, and the pressure bar is returned to the conveying mechanism 2. Subsequently, the lifting handwheel of the conveying mechanism 2 is cranked, thereby pushing the yaw positioning frame 402 to slide along the yaw slide rail base 401, causing the stator, which has been fitted with the conical shaft, to rise and move to the detection position.

[0056] The stator is raised and pushed forward onto the runout detection mechanism 4, and the pressure bar of the expansion assembly 303 is driven by the two ends of the runout detection mechanism 4. Then, the rotation detection is started: the pressure bar drives the workpiece to rotate at a constant speed, and the sensor on the runout positioning frame 402 measures the radial runout or end face runout, thereby detecting the concentricity, runout and other form and position tolerances of the stator.

[0057] After the stator is tested, the stator is transported and reset using the conveying mechanism 2, and then the hydraulic jack of the axial pressing mechanism 3 is used to press out the pressure bar.

[0058] In one specific implementation, the conveying mechanism 2 includes a workpiece support platform 201, a lifting assembly 202, and a sliding table assembly 203; the workpiece support platform 201 is installed above the lifting assembly 202; the sliding table assembly 203 is movably disposed above the worktable 1, and transports the workpiece in the workpiece support platform 201 by sliding; the lifting assembly 202 is installed on the worktable 1 and connected below the sliding table assembly 203, and is used to drive the sliding table assembly 203 to rise and fall;

[0059] The workpiece support table 201 is also connected to a handle, and the workpiece support table 201 is provided with a groove for holding the workpiece being processed.

[0060] The sliding table assembly 203 includes a sliding table base 2031, a movable frame 2032, and a sliding carriage 2033;

[0061] The slide base 2031 is set above the worktable 1. The movable frame 2032 is slidably connected to the slide base 2031. The bottom of the movable frame 2032 is connected to the lifting component 202 to achieve vertical movement. The workpiece support table 201 is connected above the slide frame 2033 via a slide rail.

[0062] The slide base 2031 is movably connected to the top of the slide base 2031 by bolts, and the lifting part of the lifting assembly 202 abuts against the slide base 2031 to achieve vertical movement.

[0063] Specifically, the top of the workpiece support platform 201 is provided with a groove that matches the motor stator workpiece for holding the workpiece, and a handle is fixed on one side to facilitate the operator to manually adjust the position of the workpiece.

[0064] The lifting assembly 202 is installed at the bottom of the worktable 1 and is driven by a hydraulic cylinder or an electric screw. The lifting stroke is 0-200mm (adjustable). The screw of the lifting part is rigidly connected to the bottom of the movable frame 2032 of the sliding table assembly 203, driving it to move vertically.

[0065] During operation, the operator places the motor stator workpiece in the groove of the workpiece support table 201. The shape of the groove matches the outer contour of the workpiece (such as round or square). The operator then fine-tunes the angle of the workpiece by using the handle to ensure that the workpiece axis is consistent with the conveying direction.

[0066] The slide 2033 moves along the horizontal slide rail of the slide base 2031, driving the workpiece support 201 and the workpiece to slide in the direction of the axial pressing mechanism 3. The stroke is controlled by the limit sensor (e.g., sliding distance 500mm). The slide rail is driven by a servo motor or pneumatic drive, and the positioning error is ≤0.5mm.

[0067] When the workpiece reaches directly below the axial pressing mechanism 3, the lifting assembly 202 is activated: the hydraulic cylinder / electric screw pushes the movable frame 2032 to rise vertically, raising the workpiece to a position coaxial with the tapered shaft pressing mechanism of the axial pressing mechanism 3; the lifting height is controlled by an encoder or limit switch (e.g., lifting height 150mm) to ensure that the center of the workpiece is aligned with the axis of the tapered shaft.

[0068] Then, the tapered shaft pressing mechanism of the axial pressing mechanism 3 descends, inserts the pressure bar into the inner hole of the workpiece, the expansion sleeve expands under pressure, and fits tightly against the inner wall of the workpiece to achieve displacement-free fixation. The probe of the sway detection mechanism 4 moves along the slide rail to the workpiece detection position, ready for measurement.

[0069] The workpiece is connected to a rotary drive device (such as a motor) via an expansion sleeve and rotates at a speed of 10-20 r / min. The yaw probe collects radial runout data in real time. After the test is completed, the lifting assembly 202 descends, and the sliding table assembly 203 sends the workpiece back to its initial position, whereby the operator unloads the workpiece.

[0070] This embodiment solves the problems of low efficiency and poor adaptability of traditional fixtures by using composite motion conveying and positioning and modular adjustable design, and has the advantages of high precision and low cost.

[0071] Example 2

[0072] As shown in Figures 1-11, this embodiment discloses a yaw meter workbench fixture for motor manufacturing. As a specific implementation, the axial pressing mechanism 3 includes a conical shaft pressing mechanism 301, a conical shaft pressing mechanism 302, and an expansion assembly 303. The conical shaft pressing mechanism 301 and the conical shaft pressing mechanism 302 are axially aligned, and the conical shaft pressing mechanism 301 is connected to the conical shaft pressing mechanism 302 through the expansion assembly 303.

[0073] The expansion assembly 303 is an expansion sleeve, with a pressure rod inside the expansion sleeve and a workpiece outside the expansion sleeve. Expansion is achieved by connecting the pressure rod to the tapered shaft pressing mechanism 301.

[0074] The conveying mechanism 2 is located below the conical shaft pressing mechanism 301 and the conical shaft pressing mechanism 302, and transports the workpiece to the sway detection mechanism 4 by sliding and lifting.

[0075] Specifically, the tapered shaft pressing mechanism 301 uses a hydraulic drive or a screw-type pressing device (such as a servo electric screw) to provide axial thrust (pressure range adjustable from 0-20MPa); its front end is equipped with a detachable pressure rod (made of hard alloy) for inserting into the inner hole of the workpiece and transmitting pressure.

[0076] The tapered shaft pressing mechanism 302 is axially aligned with the pressing mechanism 301 and uses a hydraulic ejection device to apply a reverse pulling force (e.g., 5-15 MPa) to remove the pressure bar. The tapered shaft pressing mechanism 302 also has a built-in pressure sensor to monitor the ejection force in real time and avoid overload damage to the workpiece.

[0077] The expansion assembly 303 consists of an expansion sleeve (a split elastic metal sleeve) and a pressure rod; the inner wall of the expansion sleeve fits with the conical surface of the pressure rod, and the outer wall contacts the inner hole of the workpiece; the pressure rod is pushed by the pressing mechanism 301 to make the expansion sleeve expand radially and fit tightly against the inner wall of the workpiece.

[0078] During testing, the workpiece is fixed to the pressure bar by an expansion sleeve and connected to a rotary drive device (such as a stepper motor) to drive the workpiece to rotate at a constant speed; the probe of the runout detection mechanism 4 slides along the outer circle of the workpiece to detect the radial runout (accuracy up to ±0.005mm).

[0079] This embodiment solves the problems of low efficiency, poor adaptability, and high damage rate of traditional axial pressure fixtures by using modular expansion sleeves, hydraulic / screw coordinated drive, and full-process automation, significantly improving the accuracy and economy of motor manufacturing and inspection.

[0080] Example 3

[0081] As shown in Figures 1-11, this embodiment discloses a yaw meter workbench fixture for motor manufacturing. As a specific implementation, the yaw detection mechanism 4 includes a yaw slide rail base 401 and a yaw positioning frame 402. The yaw positioning frame 402 is connected to the yaw slide rail base 401 and can slide along the length of the yaw slide rail base 401.

[0082] The 402 swing positioning frame is connected to a pressure bar via a transmission to enable rotation detection of the workpiece.

[0083] Specifically, the oscillating slide rail base 401 is fixed to the surface of the worktable 1, and adopts a high-precision linear guide (such as a ball guide), with a length covering the workpiece detection range (such as 500mm). The guide rail surface is hardened to be wear-resistant.

[0084] Positioning clamps 5 are provided at both ends of the base. The positioning clamps 5 abut against the expansion assembly and apply axial constraint force to the expansion sleeve during the testing process to prevent axial movement due to workpiece rotation or pressing / ejection force. After the stator testing is completed, the hydraulic jack of the axial pressure mechanism 3 is used to separate the pressure rod from the expansion assembly.

[0085] The yaw positioning frame 402 includes a sliding component, a detection unit, and a transmission unit. The sliding component is connected to the guide rail of the yaw slide rail base 401 via a slider, and can slide manually or electrically along the length of the base (sliding speed adjustable from 0.1 to 0.5 m / s). The detection unit includes an integrated contact displacement sensor (such as an inductive probe with an accuracy of ±0.001 mm) or a laser rangefinder, and the probe contacts the workpiece surface via an elastic arm. The transmission unit has a built-in gear set or synchronous belt, which is connected to the pressure bar of the axial pressure mechanism 3 to drive the workpiece to rotate (speed adjustable from 5 to 30 r / min).

[0086] The end of the pressure bar (from the tapered shaft pressing mechanism 301) is connected to the transmission unit of the eccentric positioning frame 402 via a coupling to achieve power transmission; the workpiece is fixed on the pressure bar by an expansion sleeve and rotates with the pressure bar to ensure no relative slippage during testing; after the conveying mechanism 2 transports the workpiece to the testing station, the lifting component 202 lifts the workpiece so that the pressure bar and the transmission unit of the eccentric positioning frame 402 are automatically connected.

[0087] This embodiment solves the problems of cumbersome operation, low accuracy, and poor scalability of traditional yaw meters by using high-precision sliding detection, integrated transmission and detection, and intelligent data management, which significantly improves the efficiency and reliability of motor manufacturing quality control.

[0088] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
