Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, and in particular to a flatness detection structure for the grinding disc of a flat grinding machine. Background Technology

[0002] A surface grinding machine is a precision machine tool used to process the surface of a workpiece to achieve extremely high flatness, parallelism, and smoothness, as well as precise thickness dimensions. Therefore, the flatness of the grinding disc of a surface grinding machine is subject to high requirements. Existing equipment for detecting the flatness of the grinding disc of a surface grinding machine includes precision levels, dial indicators, optical interferometers, and laser trackers.

[0003] The laser tracker, when in use, determines the precise three-dimensional coordinates of spatial points by emitting lasers and receiving reflected signals, collects a large amount of point data on the surface of the grinding disc, fits the plane, and calculates the flatness.

[0004] However, the existing laser trackers have low compatibility with the flat grinding machine, requiring reinstallation each time they are used, which increases the workload of installation and is not conducive to rapid detection.

[0005] To address the aforementioned issues, a flatness detection structure for the grinding disc of a flat grinding machine is proposed. Utility Model Content

[0006] The main purpose of this invention is to provide a flatness detection structure for the grinding disc of a flat grinding machine, which solves the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A flatness detection structure for the grinding disc of a flat grinding machine includes a machine base, on the top surface of the machine base symmetrically provided with sliding grooves, a power unit is provided in the sliding grooves, and a detection mechanism is installed on the power unit;

[0009] The detection mechanism includes two sets of sliding columns that slide relative to the slide groove. A drive rod and a guide rod are provided between the two sets of sliding columns. The drive rod has symmetrically arranged reciprocating threads in opposite directions. A laser detector body is mounted on both the drive rod and the guide rod.

[0010] Furthermore, the guide rod is fixed between the inner walls of the sliding column, and the laser detector body is slidably installed with the guide rod.

[0011] Furthermore, a gearbox is fixed to one side of the outer wall of the sliding column, and the drive rod rotates through the sliding column and extends into the gearbox. The laser detector body is threadedly connected to the drive rod.

[0012] Furthermore, a first motor is fixed to one side of the outer wall of the gearbox, and bevel gears that mesh with each other are fitted on the output shaft of the first motor and one end of the drive rod.

[0013] Furthermore, the power unit includes two sets of lead screws threadedly connected to the sliding column, and the lead screws are rotatably mounted to the inner wall of the sliding groove.

[0014] Furthermore, a first transmission assembly is sleeved between the outer ends of the two sets of lead screws, and a second transmission assembly is also sleeved on one set of lead screws.

[0015] Furthermore, a second motor embedded in the base is fitted at the bottom of the second transmission assembly.

[0016] Furthermore, a lower grinding disc located between the slide grooves is rotatably mounted on the top surface of the base, and an upper grinding disc that is installed in conjunction with the base is provided directly above the lower grinding disc. A display screen that is electrically connected to the laser detector body is fixed on the outer wall of the gantry frame used to install the upper grinding disc, and an operation panel is embedded in the outer wall of the base.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] This invention designs a flatness detection mechanism adapted to a flat grinding machine. The power unit drives the lead screw to rotate, which in turn moves the detection mechanism to a fixed detection position in a slide groove. Then, by utilizing the reciprocating movement mechanism of the bidirectional thread, the laser detector body can follow the rotation of the upper and lower grinding discs to perform a wide range of data acquisition. This not only makes it convenient for users to quickly detect the flatness of the grinding discs of the flat grinding machine, but also greatly improves the accuracy of the detection.

Slide groove. Detailed Implementation

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-4 As shown in the figure, the flatness detection structure of the grinding disc of the flat grinding machine provided in this embodiment includes a base 1. The top surface of the base 1 is symmetrically provided with a sliding groove 8. A power unit 7 is provided in the sliding groove 8. A detection mechanism 4 is installed on the power unit 7. The detection mechanism 4 includes two sets of sliding columns 401 that slide and limit the sliding groove 8. A drive rod 403 and a guide rod 402 are provided between the two sets of sliding columns 401. The drive rod 403 is symmetrically provided with reciprocating threads 403a in opposite directions. A laser detector body 404 is installed on both the drive rod 403 and the guide rod 402.

[0027] In the above structure, the slide groove 8 is half the width of the base 1. When the detection mechanism 4 is in the detection position, the sliding column 401 is aligned with the inner end wall of the slide groove 8, and when idle, it is aligned with the outer end wall. The reciprocating thread 403a is symmetrically arranged in opposite directions on the drive rod 403. This arrangement enables the laser detector body 404 to reciprocate in opposite directions on the guide rod 402, so that data at different positions on the grinding disc can be collected.

[0028] The guide rod 402 is fixed between the inner walls of the sliding column 401, and the laser detector body 404 is slidably installed with the guide rod 402. A gearbox 406 is fixed to one side of the outer wall of the sliding column 401. The drive rod 403 rotates through the sliding column 401 and extends into the gearbox 406. The laser detector body 404 is threadedly connected to the drive rod 403.

[0029] A first motor 405 is fixed to one side of the outer wall of the gearbox 406. The output shaft of the first motor 405 and one end of the drive rod 403 are fitted with meshing bevel gears. The diameter ratio of the bevel gear on the motor shaft to the bevel gear on the drive rod 403 is 1:2, thereby achieving the purpose of deceleration.

[0030] The power unit 7 includes two sets of lead screws 701 that are threadedly connected to the sliding column 401. The lead screws 701 are rotatably mounted to the inner wall of the slide groove 8.

[0031] A first transmission assembly 702 is sleeved between the outer ends of the two sets of lead screws 701, and a second transmission assembly 704 is also sleeved on one set of lead screws 701. Both the first transmission assembly 702 and the second transmission assembly 704 are belt and pulley structures.

[0032] The second transmission component 704 has a second motor 703 embedded in the base 1 installed at the bottom. The first motor 405 and the second motor 703 are both independently controlled.

[0033] The top surface of the base 1 is also rotatably mounted with a lower grinding disc 2 located between the slide grooves 8. Above the lower grinding disc 2 is an upper grinding disc 3 that is installed in conjunction with the base 1. The outer wall of the gantry frame used to install the upper grinding disc 3 is fixed with a display screen 6 that is electrically connected to the laser detector body 404. An operation panel 5 is embedded in the outer wall of the base 1.

[0034] In the above structure, the bottom laser head of the laser detector body 404 is 10-15cm higher than the top of the lower grinding disc 2. The top laser head of the laser detector body 404 and the upper grinding disc 3 are adaptively adjusted by a hydraulic system on the top of the upper grinding disc 3. Both the upper grinding disc 3 and the lower grinding disc 2 are driven to rotate by independent motors in opposite directions. Together with the reciprocating movement of the laser detector body 404, it can achieve wave-like detection, thereby improving the accuracy of data detection.

[0035] The back of the display screen 6 is equipped with a data processing unit connected to the laser detector body 404. It can process the data detected by the laser detector body 404 and display it on the display screen in real time for easy and intuitive viewing by the user. The operation panel 5 is used to control the first motor 405, the second motor 703, and the laser detector body 404.

[0036] The working principle of this device is as follows:

[0037] During the grinding process on the flat grinding machine, the sliding column 401 carrying the laser detector body 404 is located at one end of the outer side of the sliding groove 8, away from the upper grinding disc 3 and the lower grinding disc 2.

[0038] When flatness testing is required, the upper hydraulic system raises the upper grinding disc 3 to a certain height, allowing the laser detector body 404 to be positioned between the upper grinding disc 3 and the lower grinding disc 2. The second motor 703 is activated via the buttons on the operation panel 5, which drives the second transmission assembly 704 to rotate, thereby driving one set of lead screws 701 to rotate. This set of lead screws 701, through the first transmission assembly 702, synchronously drives the other set of lead screws 701 to rotate, so that the two sets of sliding columns 401 move synchronously within the slide groove 8 to the middle part of the machine base 1. The first motor 405 is started via the operation panel 5. After the first motor 405 is driven by the bevel gear in the gearbox 406, it transmits kinetic energy to the drive rod 403. The drive rod 403 drives two sets of opposite reciprocating threads 403a to rotate, so that the laser detector body 404 installed on the reciprocating threads 403a moves back and forth along the guide rod 402 within the thread stroke of the reciprocating threads 403a, and performs reciprocating movement detection on the working surfaces of the upper grinding disc 3 and the lower grinding disc 2. At the same time, both the upper grinding disc 3 and the lower grinding disc 2 are in the rotation mode of the working state, so that the detection laser beam of the laser detector body 404 is wave-shaped, thereby improving the data acquisition range.

[0039] The above structure allows for the compatible installation of the testing device and the flatness grinding machine, facilitating users to quickly conduct flatness testing on the flatness grinding machine, thereby reducing testing time and improving testing efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
