A motor spindle testing clamping stand

Abstract

This utility model relates to the field of motor spindle technology, and more particularly to a motor spindle testing and clamping stand. The stand includes a platform with an adjustment groove. A first clamping component and a second clamping component are disposed above the adjustment groove. Adjustment components are connected to the bottom of both the first and second clamping components. At least two lifting components connect the first and second clamping components. The first and second clamping components on the platform can clamp, fix, and rotate the spindle. The lifting components facilitate the placement and clamping of the spindle. By adjusting the rotation of the motor-driven lead screw, a drive plate moves along the lead screw axis via threaded transmission, thereby pushing the first and second clamping components to move closer or further apart synchronously. This allows for rapid adjustment of the distance between them to accommodate motor spindles of different lengths, replacing the traditional manual adjustment method and improving operational efficiency.

Description

Technical Field

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

[0002] The motor spindle is an important component of a motor. As the link between the motor and the equipment for electromechanical energy conversion, it supports rotating parts, transmits torque, and determines the relative position of rotating parts with respect to the stator. In order to ensure the stability of the motor output, the coaxiality of the motor spindle needs to be tested. During the test, a motor spindle testing clamping stand is needed for clamping and fixing.

[0003] A motor spindle coaxiality testing device with publication number CN221992605U includes a worktable with a test bracket fixed on it. This device can save testing time and improve testing efficiency, and is suitable for testing the coaxiality of motor spindles in large batches. However, the clamping frames of these existing testing devices can only clamp and fix spindles of fixed specifications, which has poor applicability. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing testing devices can only clamp and fix spindles of fixed specifications, resulting in poor applicability. This invention provides a motor spindle testing clamping table that can quickly adjust the distance between the first clamping component and the second clamping component by pushing them to move closer or further apart simultaneously to adapt to motor spindles of different lengths, replacing the traditional manual adjustment method and improving operating efficiency.

[0005] To achieve the above objectives, this utility model provides a motor spindle detection clamping stand, including a platform with an adjustment groove. A first clamping component and a second clamping component are arranged above the adjustment groove. Adjustment components are connected to the bottom of both the first and second clamping components. At least two lifting components are connected between the first and second clamping components. The adjustment component includes a mounting frame, and a lead screw is connected inside the mounting frame through a bearing seat. One end of the lead screw is connected to an adjustment motor, and a drive plate is connected to the lead screw.

[0006] As a further description of the above technical solution: the bottom of the platform is provided with support legs, a control box is provided between the two adjustment components, and a control panel is provided on the control box.

[0009] As a further description of the above technical solution: the lifting assembly includes an electric lifting rod, the lower part of which is detachably connected to the platform by bolts, and a lifting plate is connected above the electric lifting rod. A bracket is provided inside the lifting plate, and support rollers are provided on the bracket.

[0010] As a further description of the above technical solution: both the first clamping assembly and the second clamping assembly are connected to a connecting plate on their sides, and the bottom of the connecting plate is rotatably connected to a movable pulley via a bearing seat.

[0011] As a further description of the above technical solution: a limit rod is provided below the lead screw, and a limit block is provided at the bottom of the drive plate that is slidably connected to the limit rod.

[0012] As a further description of the above technical solution: the lifting plate is an arc-shaped plate.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] This invention uses a first clamping assembly and a second clamping assembly on a platform to clamp, fix, and rotate the spindle. A lifting assembly facilitates the placement and clamping of the spindle. By adjusting the rotation of the motor-driven lead screw, the drive plate moves along the lead screw axis through threaded transmission, thereby pushing the first clamping assembly and the second clamping assembly to move closer or further apart synchronously. This allows for rapid adjustment of the distance between the two to accommodate motor spindles of different lengths, replacing the traditional manual adjustment method and improving operational efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. 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 according to the specific circumstances.

[0025] like Figure 1-5As shown, the present invention provides a motor spindle testing clamping stand, including a platform 1, an adjustment groove 2 on the platform 1, a first clamping component 3 and a second clamping component 4 above the adjustment groove 2, and adjustment components 5 connected to the bottom of both the first clamping component 3 and the second clamping component 4. At least two lifting components 6 are connected between the first clamping component 3 and the second clamping component 4. The adjustment component 5 includes a mounting frame 51, and a lead screw 52 is connected inside the mounting frame 51 through a bearing seat. One end of the lead screw 52 is connected to an adjustment motor 53, and a drive plate 54 is connected to the lead screw 52.

[0026] In the technical solution of this utility model, the spindle can be clamped, fixed and rotated by the first clamping component 3 and the second clamping component 4 on the platform 1. The lifting component 6 facilitates the placement and clamping of the spindle. The motor 53 drives the lead screw 52 to rotate, and the drive plate 54 moves along the lead screw axis through the threaded transmission, thereby pushing the first clamping component 3 and the second clamping component 4 to move closer or further away synchronously. The distance between the two can be quickly adjusted to adapt to motor spindles of different lengths, replacing the traditional manual adjustment method and improving the operating efficiency.

[0027] The adjustment groove 2 provides a guide track for the movement of the clamping components, ensuring that the first clamping component 3 and the second clamping component 4 move smoothly along a straight line, while limiting their direction of movement to ensure the accuracy of the clamping position.

[0028] like Figure 1 As shown, the bottom of the platform 1 is provided with support legs 7, and a control box 8 is provided between the two adjustment components 5. The control box 8 is provided with a control panel 9. The operator sets parameters such as the speed and direction of the adjustment motor 53 and the lifting height of the electric lifting rod 61 through the control panel 9, so as to realize the automated control of the clamping component spacing adjustment and the lifting component height adjustment, reduce manual intervention, and improve the convenience and accuracy of operation. The display screen shows the operating status of each component of the platform in real time and provides prompts for abnormal conditions, so as to facilitate the operator to deal with them in time and ensure the safe operation of the equipment.

[0029] like Figure 1 and Figure 2 As shown, the first clamping assembly 3 includes a first mounting plate 31, on which a first rotating shaft 32 is mounted via a bearing. One end of the first rotating shaft 32 is connected to a first chuck 33, and the other end of the first rotating shaft 32 is connected to a driving component 34. The second clamping assembly 4 includes a second mounting plate 41, on which a second rotating shaft 42 is mounted via a bearing. One end of the second rotating shaft 42 is connected to a second chuck 43.

[0030] Specifically, the first chuck 33 and the second chuck 43 are clamped and fixed from both ends of the main shaft. The opening and closing of the jaws are adapted to motor main shafts of different diameters to provide reliable clamping force and prevent the main shaft from shaking or falling off during the inspection process. The drive unit 34 can drive the first rotating shaft 32 and the clamped main shaft to rotate, which facilitates all-round inspection of the outer surface of the main shaft. The second rotating shaft 42 provides driven support to ensure the coaxiality of the main shaft during rotation and improve the inspection accuracy.

[0031] The driving component 34 includes a driving motor, which is connected to the first rotating shaft 32 via a driving wheel and a transmission belt. The driving motor drives the first rotating shaft 32 to rotate.

[0032] like Figure 1 and Figure 3 As shown, the lifting assembly 6 includes an electric lifting rod 61, which is detachably connected to the platform 1 via bolts 10 at its bottom. A lifting plate 62 is connected above the electric lifting rod 61, and a bracket 63 is provided inside the lifting plate 62. Supporting rollers 64 are provided on the bracket 63. When the electric lifting rod 61 is working, it drives the lifting plate 62 to rise, lifting the spindle that has been inspected, so that the height of the spindle is higher than the chuck, allowing the operator to grab both ends of the spindle and easily remove it, thus speeding up the work efficiency.

[0033] The support rollers 64 are installed inside the lifting plate 62. The support rollers 64 can support the main shaft, which enhances the stability of the main shaft and does not affect the rotation of the main shaft.

[0034] Specifically, the lifting plate 62 is an arc-shaped plate.

[0035] like Figure 1 and Figure 4 As shown, the first clamping assembly 3 and the second clamping assembly 4 are both connected to the side of the connecting plate 11. The bottom of the connecting plate 11 is rotatably connected to the movable pulley 12 through the bearing seat. The connecting plate 11 and the movable pulley 12 enable the clamping assembly to slide easily along the adjustment groove 2, and cooperate with the adjustment assembly 5 to achieve rapid positioning, while reducing friction during movement and reducing energy consumption.

[0036] like Figure 1 and Figure 2 As shown, a limit rod 55 is provided below the lead screw 52, ​​and a limit block 56 is provided at the bottom of the drive plate 54, which is slidably connected to the limit rod 55. The cooperation between the limit rod 55 and the limit block 56 restricts the movement trajectory of the drive plate 54, preventing it from shifting or rotating during movement, and ensuring the linear accuracy of the clamping assembly movement.

[0037] Working principle: The spindle can be clamped, fixed and rotated by the first clamping component 3 and the second clamping component 4 on the platform 1. The lifting component 6 facilitates the placement and clamping of the spindle. The motor 53 drives the lead screw 52 to rotate, and the drive plate 54 moves along the lead screw axis through the threaded transmission, thereby pushing the first clamping component 3 and the second clamping component 4 to move closer or further away at the same time. The distance between the two can be quickly adjusted to adapt to motor spindles of different lengths, replacing the traditional manual adjustment method and improving operation efficiency.

[0038] 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 process, method, article, or apparatus.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
