Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide shaft outer diameter detection technology, and specifically to an outer diameter detection device for guide shaft machining. Background Technology
[0002] A guide shaft is a high-precision mechanical part, mainly used for precision guidance in linear motion systems. It is used in conjunction with linear bearings or other bushing products to achieve low-friction, high-precision linear motion.
[0003] In the production of guide shafts, random sampling is required to check their outer diameter to see if it is within the acceptable range. In most cases, workers use a measuring ruler to measure and check them. However, during this process, one hand holds the guide shaft and the other holds the measuring ruler. Insufficient hand stability may affect the accuracy of the measurement and cause deviations.
[0004] Therefore, an outer diameter detection device for guide shaft machining is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide an outer diameter detection device for guide shaft machining in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An outer diameter detection device for guide shaft machining includes a fixed plate, four fixed shells at the bottom of the fixed plate, lifting mechanisms for auxiliary leveling on the four fixed shells, and the lifting mechanisms on the fixed plate. Two brackets are provided at the top of the fixed plate, and a fixed frame is provided at the top of the fixed plate. A clamping mechanism for clamping and fixing the guide shaft is provided on the fixed frame, and a measuring mechanism for measuring the outer diameter of the guide shaft is provided on the clamping mechanism.
[0007] Furthermore, the lifting mechanism includes four movable columns, which are slidably mounted on the inner wall of the fixed shell. Four one-way screws are rotatably mounted on the fixed plate, and the one-way screws are threaded onto the movable columns. A knob is fixedly mounted on the top of each of the four one-way screws.
[0008] Furthermore, anti-slip pads are fixedly installed at the bottom of each of the four movable columns, and the anti-slip pads are made of rubber.
[0009] Furthermore, the clamping mechanism includes a bidirectional screw, which is rotatably mounted inside the fixed frame. Two clamping plates are threaded onto the outer wall of the bidirectional screw. A motor is fixedly mounted on the surface of the fixed frame, and the bidirectional screw is fixedly mounted on the output end of the motor.
[0010] Furthermore, telescopic dust covers are fixedly installed on both sides of the two clamping plates, and the telescopic dust covers are fixedly installed inside the fixed frame, with bidirectional screws located inside the telescopic dust covers.
[0011] Furthermore, the measuring mechanism includes a measuring ruler, which is fixedly installed on the surface of one of the clamps, and a sliding hole is passed through the surface of the other measuring ruler, and the measuring ruler is slidably installed on the inner wall of the sliding hole.
[0012] The beneficial effects of this utility model are as follows: This utility model, through the setting of a lifting mechanism, a clamping mechanism, and a measuring mechanism, allows for easy adjustment and adaptation of the placement area's flatness via the lifting mechanism during use, preventing localized suspension that could affect testing stability. The guide shaft is then placed on two supports and clamped in place by the clamping mechanism. Finally, the measuring mechanism measures the outer diameter of the guide shaft to determine if it meets the required standards. This design facilitates easy clamping and measurement of the guide shaft's outer diameter, ensuring high measurement accuracy. It also features adjustable support height to prevent suspension and maintain testing stability, simple operation, and strong practicality. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0017] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0018] The electrical components mentioned in this article are all connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can be used for control.
[0019] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. 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.
[0020] like Figure 1-2 As shown, an outer diameter detection device for guide shaft machining includes a fixed plate 1, four fixed shells 3 are provided at the bottom of the fixed plate 1, and lifting mechanisms 4 for auxiliary leveling are provided on the four fixed shells 3, with the lifting mechanisms 4 mounted on the fixed plate 1; Figure 1-2 As shown, specifically, the lifting mechanism 4 includes four movable columns 401, which are slidably installed on the inner wall of the fixed shell 3. Four one-way screws 402 are rotatably installed on the fixed plate 1, and the one-way screws 402 are threaded onto the movable columns 401. A knob 403 is fixedly installed on the top of each of the four one-way screws 402, and an anti-slip pad made of rubber is fixedly installed on the bottom of each of the four movable columns 401.
[0021] More specifically, based on the flatness of the area to be placed, the knob 403 is turned to drive the one-way screw 402 to rotate, and the moving column 401 moves longitudinally with the cooperation of the fixed shell 3 to make horizontal contact with it. The rubber anti-slip pad enhances friction resistance and reduces slippage. If the four moving columns 401 are adjusted to the same height, the height of the fixed plate 1 can be adjusted, thereby achieving adjustable support height and avoiding suspension, which would affect the stability of the test.
[0022] Two brackets 2 are provided on the top of the fixing plate 1, and a fixing frame 5 is provided on the top of the fixing plate 1. A clamping mechanism 6 for clamping and fixing the guide shaft is provided on the fixing frame 5; for example Figure 1 , Figure 3 As shown, specifically, the clamping mechanism 6 includes a bidirectional screw 601, which is rotatably mounted inside the fixed frame 5. Two clamping plates 602 are threaded onto the outer wall of the bidirectional screw 601. A motor 604 is fixedly mounted on the surface of the fixed frame 5, and the bidirectional screw 601 is fixedly mounted on the output end of the motor 604. Telescopic dust covers 603 are fixedly mounted on both sides of the two clamping plates 602, and the telescopic dust covers 603 are fixedly mounted inside the fixed frame 5. The bidirectional screw 601 is located inside the telescopic dust covers 603.
[0023] More specifically, the motor 604 is started, which drives the bidirectional screw 601 to rotate, causing the two clamping plates 602 to move closer to each other and clamp and fix the guide shaft. During this process, the four telescopic dust covers 603 are compressed and stretched respectively. The four telescopic dust covers 603 can prevent dust from adhering to the bidirectional screw 601 and avoid affecting the movement of the clamping plates 602.
[0024] The clamping mechanism 6 is equipped with a measuring mechanism 7 for measuring the outer diameter of the guide shaft; such as Figure 1 , Figure 3 As shown, specifically, the measuring mechanism 7 includes a measuring ruler 702, which is fixedly installed on the surface of one of the clamping plates 602. A sliding hole 701 is passed through the surface of the other measuring ruler 702, and the measuring ruler 702 is slidably installed on the inner wall of the sliding hole 701.
[0025] More specifically, when the two clamping plates 602 are clamping and fixing the guide shaft, the measuring ruler 702 will slide in the sliding hole 701. When the two clamping plates 602 are clamping and fixing the guide shaft, the measuring ruler 702 will stop moving. By observing the value between the two clamping plates 602 on the measuring ruler 702, the outer diameter of the guide shaft can be determined, and whether it is qualified can be judged.
[0026] In summary, during use, the lifting mechanism 4 is adjusted to fit the flatness of the placement area to avoid local suspension that could affect the stability of the test. Then, the guide shaft is placed on the two supports 2 and clamped and fixed by the clamping mechanism 6. Finally, the outer diameter of the guide shaft is measured by the measuring mechanism 7 to determine if it meets the qualified standard. This system facilitates clamping and fixing of the guide shaft for outer diameter measurement, provides high measurement accuracy, and allows for adjustable support height to avoid suspension that could affect the stability of the test. It is simple to operate and highly practical.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
