Description

Technical Field

[0001] This utility model relates to the field of cylindrical grinding machine technology, specifically to a cylindrical grinding machine measuring device. Background Technology

[0002] A grinding machine is a machine tool that uses abrasives to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasives such as oilstones, abrasive belts, and free abrasives. Grinding machines can process materials with high hardness, such as hardened steel and cemented carbide, as well as brittle materials such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as heavy-duty grinding. In order to ensure the grinding accuracy, existing grinding machines need to measure the parameters of the workpiece to be ground during grinding, so an external cylindrical grinding machine measuring device is required.

[0003] In the existing cylindrical grinding process, the accuracy of measuring the outer diameter of the workpiece often relies on the operator's experience and some relatively simple measuring tools, such as manual measurement using calipers. This measurement method is not only inefficient, but also easily affected by human factors, resulting in unstable measurement accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a measuring device for an external cylindrical grinding machine, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for an external cylindrical grinding machine, comprising a measuring table,

[0006] A pad that is fixedly installed at the bottom of the measuring table;

[0007] And a measuring component located on the side of the measuring platform;

[0008] The measuring assembly includes a measuring mechanism positioned on the side of the measuring platform;

[0009] An auxiliary mechanism is provided on the side of the measuring platform, and the auxiliary mechanism is connected to the measuring mechanism.

[0010] Preferably, there are four pads, all of the same shape and size, and the four pads are fixedly installed at the four corners of the bottom of the measuring platform, so as to support the position of the entire device.

[0011] Preferably, the measuring mechanism includes a motor, which is fixedly mounted on the top of the measuring platform. The motor extends through the top of the measuring platform to the inner wall of the measuring platform via a rotating shaft at its output end, and is driven by a lead screw. The bottom of the lead screw is rotatably connected to the inner wall of the measuring platform via a bearing. A rectangular block is mounted on the side wall of the lead screw, an adjustment plate is fixedly mounted on the front of the rectangular block, a laser rangefinder is fixedly mounted on the bottom of the adjustment plate, and a movable frame is fixedly mounted on the side wall of the adjustment plate.

[0012] Preferably, the side wall of the lead screw is threadedly connected to the inner wall of the rectangular block, and the side wall of the rectangular block is slidably connected to the inner wall of the measuring platform. When the lead screw rotates, it can move the position of the rectangular block.

[0013] Preferably, the auxiliary mechanism includes a bidirectional threaded rod and a support platform. One end of the bidirectional threaded rod is rotatably connected to the inner wall of the movable frame via a bearing. The other end of the bidirectional threaded rod extends movably through the inner wall of the movable frame to the outer side of the movable frame and is equipped with a rotating handle. A sleeve block is installed on the side wall of the bidirectional threaded rod, and a moving block is fixedly installed on the side wall of the sleeve block. A measuring plate is fixedly installed at the bottom of the sleeve block.

[0014] Preferably, the sidewall of the moving block is slidably connected to the sidewall of the moving frame, the sidewall of the measuring plate is slidably connected to the inner wall of the moving frame with a rectangular groove, and the inner wall of the sleeve block is threadedly connected to the sidewall of the bidirectional threaded rod.

[0015] Preferably, the support platform is fixedly installed on the side wall of the measuring platform, and an inclined plate is fixedly installed at the bottom of the support platform, with the other end of the inclined plate fixedly connected to the side wall of the measuring platform.

[0016] This utility model provides a measuring device for an external cylindrical grinding machine. It has the following beneficial effects:

[0017] (1) In this utility model, the operator turns on the motor, and the motor drives the lead screw to rotate through the output shaft. Since the side wall of the lead screw is threadedly connected to the inner wall of the rectangular block, the lead screw can drive the rectangular block to descend when it rotates. The rectangular block further drives the adjustment plate and the moving frame to descend. Then, the height of the workpiece can be measured by a laser rangefinder. This solves the problem that in the existing external cylindrical grinding process, the accuracy of measuring the outer diameter of the workpiece often depends on the operator's experience and some relatively simple measuring tools. Using calipers for manual measurement is not only inefficient, but also easily affected by human factors, resulting in unstable measurement accuracy.

[0018] (2) With this utility model, the operator can rotate the position of the rotating handle, which drives the position of the bidirectional threaded rod to rotate. The side wall of the bidirectional threaded rod is threadedly connected to the inner wall of the sleeve block. Therefore, when the bidirectional threaded rod rotates, it can drive the position of the sleeve block and the moving block to move. When the measuring plate contacts the side wall of the workpiece, the operator can stop rotating the rotating handle. At this time, the width of the workpiece can be measured according to the vertical movement of the moving block on the surface of the moving frame, thus improving the measurement effect of the device.

Detailed Implementation

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] Example 1: A preferred embodiment of the measuring device for an external cylindrical grinding machine provided by this utility model. Figures 1 to 4 As shown: A measuring device for an external cylindrical grinding machine, including a measuring table 1,

[0026] The pads 2 are fixedly installed at the bottom of the measuring platform 1. There are four pads 2, and the four pads 2 are all the same shape and size. The four pads 2 are fixedly installed at the four corners of the bottom of the measuring platform 1. The pads 2 can support the position of the whole device.

[0027] And the measuring component 4 is located on the side of the measuring platform 1;

[0028] The measuring component 4 includes a measuring mechanism 41 located on the side of the measuring table 1;

[0029] An auxiliary mechanism 42 is provided on the side of the measuring platform 1, and the auxiliary mechanism 42 is connected to the measuring mechanism 41.

[0030] The measuring mechanism 41 includes a motor 411, which is fixedly installed on the top of the measuring platform 1. The motor 411 extends through the top of the measuring platform 1 to the inner wall of the measuring platform 1 via a rotating shaft at its output end. A lead screw 412 is installed for transmission. The bottom of the lead screw 412 is rotatably connected to the inner wall of the measuring platform 1 via a bearing. A rectangular block 413 is installed on the side wall of the lead screw 412. An adjustment plate 415 is fixedly installed on the front of the rectangular block 413. A laser rangefinder 414 is fixedly installed on the bottom of the adjustment plate 415. A movable frame 416 is fixedly installed on the side wall of the adjustment plate 415.

[0031] In this embodiment, the side wall of the lead screw 412 is threadedly connected to the inner wall of the rectangular block 413, and the side wall of the rectangular block 413 is slidably connected to the inner wall of the measuring table 1. When the lead screw 412 rotates, it can drive the position of the rectangular block 413 to move.

[0032] In the specific implementation process, when the operator uses the device, the workpiece is installed on the surface of the support platform 426, and then the motor 411 is turned on. The motor 411 drives the lead screw 412 to rotate through the shaft at the output end. Since the side wall of the lead screw 412 is threadedly connected to the inner wall of the rectangular block 413, the lead screw 412 can drive the rectangular block 413 to descend when it rotates. The rectangular block 413 further drives the adjustment plate 415 and the moving frame 416 to descend. Then, the height of the workpiece can be measured by the laser rangefinder 414.

[0033] Example 2: Based on Example 1, a preferred embodiment of the measuring device for an external cylindrical grinding machine provided by this utility model is as follows: Figures 1 to 4 As shown: The auxiliary mechanism 42 includes a bidirectional threaded rod 421 and a support platform 426. One end of the bidirectional threaded rod 421 is rotatably connected to the inner wall of the movable frame 416 through a bearing. The other end of the bidirectional threaded rod 421 extends movably through the inner wall of the movable frame 416 to the outer side of the movable frame 416 and is equipped with a rotating handle 423. A sleeve block 422 is installed on the side wall of the bidirectional threaded rod 421. A moving block 424 is fixedly installed on the side wall of the sleeve block 422. A measuring plate 425 is fixedly installed at the bottom of the sleeve block 422.

[0034] In this embodiment, the side wall of the moving block 424 is slidably connected to the side wall of the moving frame 416, the side wall of the measuring plate 425 is slidably connected to the inner wall of the moving frame 416 with a rectangular groove, and the inner wall of the sleeve block 422 is threadedly connected to the side wall of the bidirectional threaded rod 421.

[0035] Furthermore, the support platform 426 is fixedly installed on the side wall of the measuring platform 1, and an inclined plate 427 is fixedly installed at the bottom of the support platform 426. The other end of the inclined plate 427 is fixedly connected to the side wall of the measuring platform 1.

[0036] In the specific implementation process, the operator can rotate the handle 423, which drives the bidirectional threaded rod 421 to rotate. The side wall of the bidirectional threaded rod 421 is threadedly connected to the inner wall of the sleeve block 422. Therefore, when the bidirectional threaded rod 421 rotates, it can drive the sleeve block 422 and the moving block 424 to move. When the measuring plate 425 contacts the side wall of the workpiece, the operator can stop rotating the handle 423. At this time, the width of the workpiece can be measured based on the vertical movement of the moving block 424 on the surface of the moving frame 416.
