Description

Technical Field

[0001] This utility model relates to the field of spindle component testing technology, and in particular to a spindle component testing device. Background Technology

[0002] Currently, spindle component testing devices typically use a motor to drive the spindle component via belt transmission. The motor's output shaft is connected to a pulley on the spindle component via a belt. The performance of the spindle component under different operating conditions is tested by adjusting the motor speed. The height and forward / backward position of the motor need to be adjusted according to the spindle component model. Currently, this is mostly done by manually adjusting the large nut on the motor base. This requires repeated rotation of the fixing component, which is cumbersome and time-consuming when changing spindle models. For some spindle components of certain sizes, the motor travel is limited and cannot be adapted, requiring additional customization and replacement of supports of different heights, increasing costs and time. Utility Model Content

[0003] The purpose of this invention is to provide a spindle component testing device that can solve the above-mentioned technical problems.

[0004] This utility model provides a spindle component testing device, including a testing frame. The top of the testing frame is provided with a support for supporting the spindle component. A motor device is provided on one side of the support. The motor device includes a motor base. A motor bracket is slidably connected to the upper part of the motor base in the horizontal direction. A support block is fixedly provided on the motor bracket. A side plate is fixedly connected to one side of the support block. A motor plate is slidably connected to the side plate in the vertical direction. A working motor with an output shaft in the vertical direction is fixedly connected to the motor plate.

[0005] Furthermore, the test frame includes an assembly support, on which a top platform is fixedly mounted. The support is fixed to the top platform by bolts, and the motor base is welded to the top platform.

[0006] Furthermore, the assembly support is composed of H-beams, steel plates welded together and bolted together, and the top platform is composed of H-beams, steel plates welded together and bolted to the top of the assembly support.

[0007] Furthermore, one side of the assembly support is provided with an inclined ladder connecting to the top platform.

[0008] Furthermore, a guardrail is provided around the top platform.

[0009] Furthermore, the motor base and the motor bracket are slidably connected by a guide rail slider assembly, and an electric push rod for driving its sliding is provided on one side of the motor bracket, the output end of which is fixedly connected to the side plate.

[0010] Furthermore, the motor plate and the side plate are slidably connected by a guide rail slider assembly. A servo motor is provided above the motor plate, and a lead screw is fixedly connected to the output end of the servo motor. A connecting block is fixedly provided on the side of the motor plate near the side plate, and the lead screw passes through the connecting block and is threadedly connected to it.

[0011] Furthermore, a rib is connected between the side plate and the support block.

[0012] Furthermore, the height adjustment range of the working motor is 0-500mm, and the horizontal adjustment range is 0-200mm.

[0013] Furthermore, the servo motor and electric push rod are controlled by a remote control and have a self-locking function, which allows the motor to move and stop at any time.

[0014] Beneficial effects:

[0015] This invention simplifies the adjustment process by making the motor base and motor bracket horizontally slidably connected, and the motor plate and side plate vertically slidably connected. This allows for both horizontal and vertical position adjustment of the working motor, eliminating the need for repeated tightening of fixing parts, thus significantly reducing operational difficulty. When different models of spindle components need to be replaced, the working motor position can be quickly adjusted to accommodate them, greatly shortening changeover time and improving the efficiency of the testing device. The working motor can be adjusted over a wider range of positions by sliding the motor bracket horizontally and the motor plate vertically, accommodating more spindle components of different sizes and models. This avoids the need for custom-made supports due to limited travel, thereby reducing equipment and time costs. Through the sliding connection between the various components, the working motor position can be flexibly adjusted while ensuring the stability of spindle component testing. This meets the testing requirements of different models of spindle components under different working conditions, improving the versatility and applicability of the testing device.

[0026] Example 1

[0027] A spindle component testing device, such as Figure 1-5 As shown, the system includes a test frame 1, which serves as the foundational load-bearing structure for the entire device, providing a stable support platform for subsequent testing operations. At the top of the test frame 1, a support 3 is specifically designed to support the main spindle component 16. The structural design of this support fully considers the shape and installation requirements of the main spindle component, ensuring precise and stable fixation and preventing any shaking or displacement during testing, thus guaranteeing the accuracy of the test data. Specifically, the main spindle component is hoisted onto the support using a crane. The support has mounting holes, and the main spindle component is secured to the support with bolts. The support and the entire test frame are permanently fixed together.

[0028] On one side of the support 3, a motor unit 2 is provided, which is the component that provides power for the test run. The motor unit 2 specifically includes a motor base 8, which is the basic support for the motor unit and provides a stable platform for subsequent component installation. A motor bracket 9 is slidably connected to the upper part of the motor base 8. This sliding connection allows the motor bracket 9 to move flexibly in the horizontal direction according to actual test requirements, thereby adjusting the horizontal position of the motor. A support block 22 is fixedly installed on the motor bracket 9, serving as a connection and support, providing a stable support point for subsequent component installation. A side plate 19 is fixedly connected to one side of the support block 22. The side plate 19 further enhances the stability of the entire motor unit structure and also provides a foundation for the installation of the motor plate 10. The side plate 19 is slidably connected to the motor plate 10 in the vertical direction. This vertical sliding connection allows the motor plate 10 to move vertically as needed, thereby adjusting the height position of the motor. A working motor 11 with its output shaft in the vertical direction is fixedly connected to the motor plate 10. The working motor 11 serves as a power source, and the direction of its output shaft is set to match the testing requirements of the main shaft component, thus providing appropriate power output for the test run.

[0029] Specifically, the test frame 1 comprises an assembly support 4, which is the main support structure of the test frame, bearing the weight of the entire device and various forces generated during the test. A top platform 5 is fixedly installed on top of the assembly support 4. The top platform 5 is the main working platform for installing the spindle components and conducting test operations; its flat surface provides a stable foundation for all operations. The support 3 is fixed to the top platform 5 with bolts. The motor base 8 is fixed to the top platform 5 by welding. Welded connections are characterized by high strength and good stability, ensuring that the motor base 8 will not shift or loosen during motor operation and the entire test process, thus guaranteeing the stability of the motor device. The assembly support 4 is constructed using H-beams and steel plates as the main materials, assembled through a combination of welding and bolting. H-beams have advantages such as reasonable cross-sectional dimensions, high strength, and light weight, providing strong load-bearing capacity for the assembly support; steel plates are used to fill and connect the gaps between the H-beams, enhancing the overall structural stability of the assembly support. Welding securely connects H-beams and steel plates to form a unified frame structure, while bolts are used for connections in areas requiring detachment or easy adjustment, making the assembly support more flexible in manufacturing and subsequent maintenance. The top platform 5 is also constructed from welded H-beams and steel plates. The H-beams serve as the framework of the top platform, ensuring its structural strength, while the steel plates are welded to the top of the H-beams, creating a smooth working surface. The top platform is bolted to the top of the assembly support, ensuring a secure connection while facilitating disassembly and maintenance when needed.

[0030] Furthermore, to facilitate safe and convenient access for operators to the top platform, an inclined ladder 6 connecting to the top platform 5 is installed on one side of the assembly support. Considering the safety of operators working on the top platform, a guardrail 7 is installed around the top platform 5.

[0031] The sliding connection between the motor base 8 and the motor bracket 9 is achieved through the guide rail slider assembly 14. The guide rail slider assembly consists of a guide rail and a slider. The guide rail is fixed to the motor base, and the slider is fixedly connected to the motor bracket. The slider can slide smoothly along the guide rail, thereby enabling the motor bracket to move horizontally. On one side of the motor bracket 9, an electric push rod 15 is provided to drive its sliding. The electric push rod 15 is a device that converts electrical energy into linear motion mechanical energy, possessing advantages such as simple structure, convenient operation, and stable thrust. The output end of the electric push rod 15 is fixedly connected to the side plate 19. When the electric push rod 15 is working, its output end extends or retracts, thereby driving the side plate 19 and the motor bracket 9 connected to the side plate 19 to slide horizontally along the guide rail slider assembly. This achieves automatic adjustment of the horizontal position of the working motor, improving the convenience of operation and the accuracy of adjustment.

[0032] The motor plate 10 and the side plate 19 are also slidably connected via a guide rail slider assembly. This guide rail slider assembly operates on the same principle as the one between the motor base 8 and the motor bracket 9. The guide rail is fixed to the side plate, and the slider is fixedly connected to the motor plate, allowing the motor plate to slide smoothly vertically along the side plate. A servo motor 12 is positioned above the motor plate 10. A lead screw 13 is fixedly connected to the output end of the servo motor 12. A lead screw is a transmission component that converts rotational motion into linear motion. A connecting block 21 is fixedly positioned on the side of the motor plate 10 near the side plate 19. The lead screw 13 passes through the connecting block 21 and is threadedly connected to it. When the servo motor 12 operates, its output end drives the lead screw 13 to rotate. Due to the threaded connection between the lead screw 13 and the connecting block 21, the rotational motion of the lead screw 13 is converted into linear motion of the connecting block 21, thereby driving the motor plate 10 to move vertically along the guide rail slider assembly. This achieves precise adjustment of the working motor's height, meeting the requirements for the working motor's height under different testing conditions. To enhance the strength and stability of the connection between the side plate 19 and the support block 22, a rib plate 20 is connected between the side plate and the support block. The rib plate is usually made of steel plate and is generally triangular in shape.

[0033] The height adjustment range of the working motor is set from 0-500mm. This range can meet the height requirements of most different models and specifications of spindle components during testing, ensuring precise alignment between the working motor and the spindle component. The horizontal adjustment range is 0-200mm. Similarly, this horizontal adjustment range can adapt to the testing needs of different spindle components, ensuring the working motor achieves the optimal relative position with the spindle component in the horizontal direction, guaranteeing smooth testing. The servo motor and electric actuator are controlled by a remote control and feature a self-locking function, allowing for easy movement and locking of the motor.

[0034] Working and usage process:

[0035] Operators ascend to the top platform 5 via the inclined ladder 6 and use a crane to hoist the spindle component 16 to be tested above the support 3. The crane position is slowly adjusted to precisely align the mounting holes of the spindle component 16 with those on the support 3. Bolts are then passed through the corresponding mounting holes to securely fix the spindle component 16 to the support 3. Since the support 3 is fixed to the top platform 5 with bolts and remains fixed to the test frame 1, this process ensures that the spindle component 16 is stable and does not wobble after installation, laying the foundation for the accuracy of subsequent test runs. After installation, operators must double-check the bolt tightness to prevent displacement during testing.

[0036] After the main shaft assembly 16 is hoisted onto the top support 3, the pulley 17 is installed on the top of the main shaft assembly 16. The height of the working motor 11 is adjusted to be flush with the pulley 17 by the remote control. The belt 18 is installed on the pulley 17 and the motor 11. The working motor 11 is moved back and forth by the remote control to tighten the belt 18.

[0037] The purpose of the above adjustments is to achieve a precise fit between the working motor 11 and the spindle assembly 16, including adjustments in both the vertical and horizontal directions:

[0038] Vertical position adjustment: The operator starts the servo motor 12 via remote control, and the output of the servo motor 12 drives the lead screw 13 to rotate. Since the lead screw 13 passes through the connecting block 21 on one side of the motor plate 10 and is threadedly connected to it, and the motor plate 10 is slidably connected to the side plate 19 via the guide rail slider assembly (the guide rail is fixed to the side plate 19, and the slider is connected to the motor plate 10), the rotational motion of the lead screw 13 is converted into the linear motion of the connecting block 21, which drives the motor plate 10 to slide smoothly along the side plate 19 in the vertical direction, thereby adjusting the height of the working motor 11. Within the height adjustment range of 0-500mm, after adjusting the working motor 11 to the height matching the spindle component 16, the servo motor 12 is turned off. Its self-locking function ensures that the motor plate 10 and the working motor 11 are locked at the current height position.

[0039] Horizontal Position Adjustment: The operator controls the electric push rod 15 via remote control. The output end of the electric push rod 15 extends or retracts, driving the side plate 19, which is fixedly connected to it, to move. Because the side plate 19 is fixed to the motor bracket 9, and the motor bracket 9 is slidably connected to the motor base 8 via the guide rail slider assembly 14 (the guide rail is fixed to the motor base 8, and the slider is connected to the motor bracket 9), the motor bracket 9 will move smoothly in the horizontal direction along the guide rail slider assembly 14, thereby driving the working motor 11 to move synchronously. According to the position requirements of the spindle component 16, within the horizontal adjustment range of 0-200mm, after adjusting the working motor 11 to a suitable horizontal position, the electric push rod 15 is stopped by remote control. Its self-locking function keeps the motor bracket 9 and the working motor 11 in the current horizontal position.

[0040] After adjusting the position of the working motor 11, confirm that the connection between the output shaft of the working motor 11 and the spindle assembly 16 meets the test requirements. The operator starts the working motor 11 from a safe area using a remote control. The working motor 11 outputs power to drive the spindle assembly 16, initiating the trial run. During the test, the operator observes the operating status of the spindle assembly 16 and records the test data using relevant testing instruments.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
