Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machining, in particular to a multi-station measuring device. Background Art
[0002] In the field of modern machining, a frequent challenge is the precision machining of the external diameter of multi-level complex workpieces, especially for high-precision components such as engine camshafts and transmission shafts. This type of machining not only tests the limits of technology but also places stringent demands on cost control and production efficiency.
[0003] Traditionally, to meet this high-precision measurement requirement, companies have often relied on imported variable-diameter measuring equipment. This not only results in high initial investment but also comes with lengthy lead times, severely restricting the flexibility of production plans and the timeliness of order fulfillment. On the other hand, while U-turn machining can provide a workaround, it inevitably sacrifices efficiency and significantly increases costs. Furthermore, the compact layout and space constraints of the workbench make it difficult to simultaneously install multiple measuring devices, a technical challenge that urgently needs to be addressed. Utility Model Content
[0004] The purpose of this utility model is to propose and design a multi-station measuring device to address the problems of high cost and long delivery cycle of imported variable diameter measuring equipment used in the existing multi-level complex workpiece external circle processing and low processing efficiency of traditional workpiece turning measurement.
[0005] The technical solution adopted by the utility model to solve the above technical problems is: a multi-station measuring device, including a mounting seat, a bracket fixed on the mounting seat, a vertical guide rail provided on the bracket, a mounting plate slidably installed on the vertical guide rail, a first telescopic cylinder installed on the bracket, the telescopic rod of the first telescopic cylinder is connected to the mounting plate, the first telescopic cylinder can drive the mounting plate to slide along the vertical guide rail, a fixed seat plate is installed on the mounting plate, a measuring device is installed on the fixed seat plate, the measuring device is tilted and arranged to form a non-zero angle with the vertical guide rail, where the fixed seat plate is tilted, the measuring device is installed on the plate surface of the fixed seat plate, so that the measuring device is tilted. When in use, the device can be installed on the machine tool bed through the mounting base and fixed thereon, and does not move with the movement of the worktable, so as not to affect the normal operation of the machine tool. The measuring device is arranged at an angle so that it avoids the workpiece when moving up and down along the vertical guide rail to facilitate its measurement. During measurement, the measuring device moves up and down to measure the bottom and top positions of the outer circle at the first location, thereby measuring the outer circle diameter of the workpiece at the first location. Then the machine tool drives the workpiece to move so that the second outer circle on the workpiece moves to the position of the measuring device. Similarly, the outer circle diameter of the second location is measured by the measuring device, thereby realizing the measurement of the outer circle diameter of the workpiece at different locations.
[0006] Furthermore, a buffer pad is provided on the bracket and is located below the mounting plate. The buffer pad is provided to prevent the measuring device from being affected by its own gravity when it falls and causing a large acceleration, thereby affecting the measurement accuracy.
[0007] Furthermore, a groove is provided at the bottom of the mounting seat, which can avoid the spindle drive box on the machine tool, so that the mounting seat can be stably mounted on the machine tool body by crossing the spindle drive box, thereby not affecting the normal operation of the machine tool.
[0008] Furthermore, flanges are provided at the bottom of both side walls of the mounting seat, and connecting holes are provided on the flanges. When in use, bolts are passed through the connecting holes on the flanges to fix the mounting seat to the machine tool.
[0009] Furthermore, a second telescopic cylinder is provided on the bracket, and a limit hole is provided on the mounting plate, into which the telescopic rod of the second telescopic cylinder can be inserted. When the machine tool is not in the machining state, the telescopic rod of the second telescopic cylinder is extended and inserted into the limit hole of the mounting plate, thereby locking it, preventing the mounting plate and the measuring device mounted thereon from falling, thereby preventing it from falling.
[0010] Furthermore, a second telescopic cylinder is fixed to the back of the bracket, and the mounting plate is located on the front of the bracket. The telescopic rod of the second telescopic cylinder passes through the bracket. Because the mounting plate needs to slide up and down, in order to reduce the space occupied by the front of the bracket and not affect the sliding of the mounting plate, the second telescopic cylinder is fixed to the back of the bracket.
[0011] Furthermore, a reinforcing sleeve is installed on the telescopic rod of the second telescopic cylinder to improve the strength of the telescopic rod of the second telescopic cylinder and achieve a more stable locking function.
[0012] Furthermore, the first telescopic cylinder is a rodless cylinder, which needs to be controlled by a center-sealed electromagnetic valve when in use to prevent it from automatically falling after an abnormal gas outage for a long time. The second telescopic cylinder is an ordinary cylinder.
[0013] Furthermore, a pad is fixed on the mounting plate, which is connected to the vertical guide rail via a slider. The vertical guide rail is a linear guide rail. The use of a linear guide rail greatly reduces friction resistance, avoids wear of mechanical parts caused by long-term movement, and increases service life.
[0014] Furthermore, the measuring device is an external circle measuring instrument or an end surface measuring instrument, which can be moved close to and away from the workpiece by means of a cylinder control, thereby measuring the bottom position and the top position of the external circle of the workpiece.
[0015] It can be seen from the above technical solutions that the present invention has the following advantages:
[0016] This solution provides a multi-station measuring device that can be mounted on the machine tool bed via a mounting bracket, ensuring it remains stationary and independent of the worktable's movement, thus maintaining normal machine operation. The measuring device is tilted so that it avoids the workpiece as it moves up and down along the vertical guide rails, facilitating measurement. During measurement, the measuring device moves up and down to measure the bottom and top of the first outer diameter, thereby determining the workpiece's outer diameter at the first location. The machine tool then drives the workpiece to move the second outer diameter to the measuring device's location. Similarly, the measuring device measures the second outer diameter, enabling measurement of outer diameters at different locations on the workpiece. This simple structure reduces significant costs and provides quick and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0021] like Figure 1As shown, this specific embodiment provides a multi-station measuring device, including a mounting base 1, a groove is provided at the bottom of the mounting base 1, flanges are provided at the bottom of the two side walls of the mounting base 1, and connecting holes are provided on the flanges. When in use, it is fixed to the machine tool by passing bolts through the connecting holes on the flanges, and the groove is set to avoid the spindle drive box on the machine tool, so as not to affect the normal operation of the machine tool. A bracket 2 is fixed on the mounting seat 1, and a vertical guide rail 5 is provided on the bracket 2. A slider 6 is installed on the vertical guide rail 5, and a pad 7 is fixed on the slider 6. A mounting plate 8 is fixed to the pad 7, and the mounting plate 8 can slide on the vertical guide rail 5 through the slider 6. A first telescopic cylinder 11 is installed on the bracket 2. The first telescopic cylinder 11 is a rodless cylinder and needs to be controlled by a mid-sealed solenoid valve when in use to avoid automatic falling after a long period of abnormal gas outage. The telescopic rod of the first telescopic cylinder 11 is connected to the mounting plate 8. The first telescopic cylinder 11 can drive the mounting plate 8 to slide along the vertical guide rail 5. A fixed seat plate 9 is installed on the mounting plate 8, and a measuring device 10 is installed on the fixed seat plate 9. The measuring device 10 is tilted and arranged to form a non-zero angle with the vertical guide rail 5. The measuring device 10 is tilted so that it avoids the workpiece when moving up and down along the vertical guide rail 5.
[0022] Among them, a buffer pad 12 is provided on the bracket 2, and the buffer pad 12 is located below the mounting plate 8. By providing the buffer pad 12, the measuring device 10 is prevented from being affected by its own gravity when falling and having a larger acceleration, which affects the measurement accuracy.
[0023] Among them, the bracket 2 is provided with a second telescopic cylinder 3, which is an ordinary cylinder. The mounting plate 8 is provided with a limit hole. The telescopic rod of the second telescopic cylinder 3 can be inserted into the limit hole. When the machine tool is not in the processing state, the telescopic rod of the second telescopic cylinder 3 is extended and inserted into the limit hole of the mounting plate 8 to be locked, thereby preventing the mounting plate 8 and the measuring device 10 installed thereon from falling, thereby preventing the mounting plate 8 and the measuring device 10 installed thereon from falling. The second telescopic cylinder 3 is fixed to the back of the bracket 2, and the mounting plate 8 is located in the front of the bracket 2. The telescopic rod of the second telescopic cylinder 3 passes through the bracket 2. Since the mounting plate 8 needs to slide up and down, in order to reduce the space occupied by the front of the bracket 2 and not affect the sliding of the mounting plate 8, the second telescopic cylinder 3 is fixed to the back of the bracket 2. Among them, a reinforcing sleeve 4 is installed on the telescopic rod of the second telescopic cylinder 3 to increase the strength of the telescopic rod of the second telescopic cylinder 3 and achieve a more stable locking function.
[0024] In addition, the measuring device 10 is an external circle measuring instrument or an end surface measuring instrument, which can be moved close to and away from the workpiece by means of a cylinder control, thereby measuring the bottom position and the top position of the external circle of the workpiece.
[0025] The operating principle is as follows: During measurement, the first telescopic cylinder 11 drives the mounting plate 8 along the vertical guide rail 5, thereby creating space for the measuring device 10 to move up and down. The measuring device 10 moves up and down to measure the bottom and top positions of the first outer circle, thereby measuring the outer diameter of the workpiece at the first location. The machine tool then drives the workpiece to move the second outer circle of the workpiece to the position of the measuring device 10. Similarly, the measuring device 10 measures the outer diameter of the second location, thus achieving outer diameter measurement at different locations on the workpiece.
