Technical Field
[0001] This utility model relates to the technical field of perpendicularity detection devices, and in particular to a simple detection device for the perpendicularity of a cylinder. Background Technology
[0002] Currently, in industrial production and machining processes, the perpendicularity and concentricity of cylindrical workpieces are among the important parameters affecting their assembly accuracy and working performance. To ensure product quality, it is usually necessary to inspect the perpendicularity of the cylinder. In existing technologies, high-precision coordinate measuring machines, laser inspection equipment, or customized special measurement platforms are widely used to complete this type of inspection. These devices are expensive and bulky, which not only places high demands on the user's operating skills, but also presents inconveniences in terms of handling, carrying, and on-site use.
[0003] Existing technologies for cylindrical perpendicularity inspection have the following main drawbacks: First, while widely used inspection equipment such as coordinate measuring machines and laser inspection systems have high precision, their overall structure is complex and costly, making them difficult to popularize in small and medium-sized processing enterprises or on-site inspection scenarios. Second, such equipment is large and heavy, making it inconvenient to handle and carry, which limits its application in mobile operations or confined spaces. Third, some simple inspection methods, such as manual visual inspection or the use of conventional measuring tools with a support, have large operational errors and unstable inspection results, failing to meet the requirements for high-precision inspection.
[0004] Furthermore, we disclose a simple detection device for the perpendicularity of a cylinder to meet the practical needs of existing detection devices, which are generally characterized by high cost, large size, and inconvenience in carrying. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a simple detection device for the perpendicularity of a cylinder, so as to solve the problems of high cost, large size and inconvenience of carrying out the detection devices in the prior art.
[0006] To achieve the above objectives, this utility model provides a simple device for detecting the verticality of a cylinder, comprising a base platform, a groove formed on one side of the middle portion of the base platform, a fixed workpiece support and a movable workpiece support respectively arranged on both sides of the inner side of the groove, a positioning module provided on the movable workpiece support for limiting the cylinder, a second upright fixedly connected to a corner on one side of the upper end face of the base platform, a second sliding sleeve and a third sliding sleeve slidably connected to the second upright, the third sliding sleeve being located at the lower end of the second sliding sleeve, a second dial indicator installed on the side of the second sliding sleeve near the fixed workpiece support, a pin fixedly connected to the side of the third sliding sleeve near the fixed workpiece support, a first upright fixedly connected to one side of the middle portion of the upper end face of the base platform, a first sliding sleeve slidably connected to the first upright, and a first dial indicator installed on the outer wall of the first sliding sleeve near the fixed workpiece support.

[0008] Preferably, the upper ends of both the fixed workpiece support and the movable workpiece support are arc-shaped. The fixed workpiece support is fixedly connected to the slide groove on the side near the second upright, and the movable workpiece support is slidably connected to the slide groove.
[0009] Preferably, the lower end of the movable workpiece support is connected to a screw, one end of which is engaged and rotatably connected to the fixed workpiece support, and the end of the screw away from the fixed workpiece support extends out of the base platform and is equipped with a turntable.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 4 As shown, a simple device for detecting the verticality of a cylinder includes a base platform 1. A groove 2 is provided on one side of the upper middle part of the base platform 1. A fixed workpiece support 13 and a movable workpiece support 14 are respectively provided on both sides of the inside of the groove 2. A positioning module is provided on the movable workpiece support 14. The positioning module is used to limit the cylinder. A second upright 7 is fixedly connected to one corner of the upper end face of the base platform 1. A second sliding sleeve 8 and a third sliding sleeve 9 are slidably connected to the second upright 7. The third sliding sleeve 9 is located at the lower end of the second sliding sleeve 8. A second dial indicator 12 is installed on the side of the second sliding sleeve 8 near the fixed workpiece support 13. A pin 19 is fixedly connected to the side of the third sliding sleeve 9 near the fixed workpiece support 13. A first upright 5 is fixedly connected to one side of the upper middle part of the base platform 1. A first sliding sleeve 6 is slidably connected to the first upright 5. A first dial indicator 11 is installed on the outer wall of the first sliding sleeve 6 near the fixed workpiece support 13.
[0024] This device aims to overcome the shortcomings of existing testing equipment, such as high cost, large size, inconvenience to carry, and insufficient accuracy of simple testing methods. The device has a simple structure, is easy to transport, and is suitable for on-site operations and the rapid measurement needs of small and medium-sized processing enterprises. The device includes a base platform 1, a fixed workpiece support 13, and a movable workpiece support 14. The upper ends of the supports are all arc-shaped to stably support the cylindrical workpiece. The movable support is slidably connected via a slide groove 2 and is precisely clamped by adjustment using a screw 4 and a turntable 3. Simultaneously, a positioning module is installed on the support, using a combination of a contact spring 18, a contact post 16, and a ball bearing 17 to axially limit the workpiece, improving clamping stability. Two uprights and three sets of sliding sleeve mechanisms are set on the platform, each equipped with two dial indicators and one ejector pin 19. The sliding sleeve positions can be locked with screws to ensure structural stability during measurement. In use, the ejector pin 19 is aligned with the center of the cylinder, and the dial indicators measure the end face and outer circle respectively, reading the deviation data to obtain perpendicularity and concentricity information. This device is not only compact and easy to use, but also possesses good practicality and economy.
[0025] Furthermore, such as Figure 1 As shown, the third sliding sleeve 9, the second sliding sleeve 8, and the first sliding sleeve 6 are all threaded with locking screws 10. One end of the locking screws 10 on the third sliding sleeve 9, the second sliding sleeve 8, and the first sliding sleeve 6 abuts against the outer wall of the second upright 7 and the first upright 5, respectively.
[0026] The third sliding sleeve 9, the second sliding sleeve 8, and the first sliding sleeve 6 are all equipped with locking screws 10 on their exteriors, with one end of each screw abutting against the outer wall of the corresponding second upright 7 and first upright 5, respectively. This structure serves to adjust and lock the position of the sliding sleeves on the uprights. During use, the operator can loosen the locking screws 10 according to the size and position requirements of the cylinder being tested, allowing the sliding sleeves to slide on the uprights to adjust the corresponding detection positions of the first dial indicator 11, the second dial indicator 12, and the pin 19. After adjusting to the appropriate height, the locking screws 10 are tightened to ensure a tight fit between the sliding sleeves and the outer wall of the uprights, thus fixing the testing device and ensuring the stability and non-displacement of the positions of each component during measurement. This guarantees the accuracy and repeatability of the verticality test. This structure not only facilitates operation but also improves the overall stability and reliability of the measurement.
[0027] Furthermore, such as Figures 1 to 4As shown, the upper ends of both the fixed workpiece support 13 and the movable workpiece support 14 are arc-shaped. The fixed workpiece support 13 is fixedly connected to the slide groove 2 on the side near the second upright 7. The movable workpiece support 14 is slidably connected to the slide groove 2. The lower end of the movable workpiece support 14 is connected to a screw 4. One end of the screw 4 is engaged and rotatably connected to the fixed workpiece support 13. The end of the screw 4 away from the fixed workpiece support 13 extends out of the base platform 1 and is equipped with a turntable 3. The positioning module includes a connecting frame 15 fixedly connected to the end face of the movable workpiece support 14 away from the fixed workpiece support 13. The upper end of the connecting frame 15 is fixedly connected to a contact spring 18 on the side near the movable workpiece support 14. The end face of the contact spring 18 away from the connecting frame 15 is fixedly connected to a contact post 16. The side of the contact post 16 near the movable workpiece support 14 is engaged and rotatably connected to a ball bearing 17.
[0028] The above structure achieves stable clamping and precise positioning of the cylindrical workpiece through the cooperation of the fixed workpiece support 13 and the movable workpiece support 14. Both supports have arc-shaped upper ends to effectively conform to the shape of the cylinder and enhance contact stability. The fixed workpiece support 13 is installed on the side of the slide groove 2 near the second upright 7 as a reference. The movable workpiece support 14 is positioned via the slide groove 2, and its lower end is connected to a screw 4. Rotating the external turntable 3 drives the screw 4 to rotate, allowing the movable workpiece support 14 to move smoothly along the slide groove 2, thereby clamping or releasing the cylinder. To further ensure the axial stability of the workpiece, the movable workpiece support... A positioning module is also provided on one side of the frame 14, including a connecting frame 15, a contact spring 18, a contact column 16 and a ball bearing 17 assembly. When in use, the ball bearing 17 in this module presses against the end of the workpiece through the pre-tensioning action of the spring, which not only prevents the workpiece from moving axially, but also automatically adapts to slight deviations during the clamping process, improving clamping flexibility and positioning accuracy. The overall usage steps are as follows: first, place the workpiece horizontally on the two supports, rotate the turntable 3 to adjust the position of the movable workpiece support 14, so that it gradually approaches and clamps the workpiece. At the same time, the positioning module completes the limit after contacting the end face of the workpiece, ensuring that the posture of the cylinder is fixed and the measurement reference is uniform during the detection process.
