Description

Technical Field

[0001] This invention relates to the field of cutting tool inspection technology, and in particular to a cutting tool runout detection table. Background Technology

[0002] Tool runout refers to the deviation of the tool tip from the spindle axis during tool rotation. Tool runout mainly includes radial runout and axial runout. The former is manifested as the periodic reciprocating motion of the tool tip along the radial direction, while the latter is manifested as the periodic axial movement of the tool tip. The existence of tool runout affects cutting accuracy and surface quality, accelerates tool wear and breakage, and reduces machining efficiency and lifespan.

[0003] Currently, commonly used methods for tool runout detection include contact static detection methods and laser non-contact dynamic detection methods. Laser non-contact dynamic detection methods use a laser beam to perform single-point or multi-point scanning measurements on a rotating tool, and calculate the runout of the tool tip based on the position and time of laser beam obstruction. This method can dynamically measure the tool at the operating speed and is suitable for tools of various types and sizes. However, due to the influence of measurement accuracy, it is necessary to control the tool to rotate at a constant speed near the laser beam during the detection process. Existing tool runout detection stands may not be able to drive tools of various sizes and models to rotate at a constant speed, thus making it impossible to detect tools of various sizes and models. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a tool runout detection table to solve the problem that existing tool runout detection tables cannot detect tools of various sizes and types.

[0012] Furthermore, the base plate is equipped with a tool runout detection device for detecting tool runout.

[0013] Furthermore, the roller is provided with a rubber pad.

[0014] Furthermore, the outside of the rotating rod is provided with anti-slip texture.

[0015] The beneficial effects of this invention are as follows: As can be seen from the above description, the tool runout detection table provided by this invention, by setting a second spring, controls the moving plate to move downward so that the positioning wheel abuts against the top of the tool, and continues to move the top plate downward so that the bottom of the top plate contacts the top of the moving plate, ensuring that the elastic force of the second spring can be fully applied to the tool through the positioning wheel, thus fixing the tool to the support frame, and thereby fixing tools of different sizes to the support frame; starting the second motor drives the roller to rotate, the roller drives the rotating rod to rotate, the rotating rod drives the drive gear to rotate through the connecting shaft, the drive gear drives the first gear and the second gear to rotate synchronously, thereby driving the first belt and the second belt to rotate synchronously, so as to drive tools of different sizes to rotate at a uniform speed.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a tool runout detection table includes a base plate 1, a support 2 mounted on the base plate 1, and further includes:

[0030] At least one set of support frames 4 are disposed on the base plate 1. The support frame 4 includes a housing 401. At least two first rotating shafts 402 and at least two second rotating shafts 405 are disposed inside the housing 401. A first belt 403 and a second belt 406 are respectively disposed on the at least two first rotating shafts 402 and the at least two second rotating shafts 405. The first belt 403 and the second belt 406 pass through the top of the housing 401 and protrude outward. A first gear 404 is disposed on the first rotating shaft 402 located at the bottom, and a second gear 407 is disposed on the second rotating shaft 405 located at the bottom. A connecting shaft 409 is rotatably connected inside the housing 401. A drive gear 408 that meshes with the first gear 404 and the second gear 407 is disposed on the connecting shaft 409.

[0031] One end of the rotating rod 3 is rotatably connected to the bracket 2, and the other end is fixedly connected to the connecting shaft 409;

[0032] The drive mechanism 5 is mounted on the base plate 1 and is used to drive the rotating rod 3 to rotate.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, the drive mechanism 5 includes a support plate 501, on which a shaft 502 is rotatably connected. One end of the shaft 502 has a connecting arm 503, and the other end has a first transmission gear 504. A first motor 505 is mounted on the base plate 1. A second transmission gear 506, meshing with the first transmission gear 504, is mounted on the output shaft of the first motor 505. A limit hole 511 is formed on the connecting arm 503. Two sets of slide rods 508 are provided on one side of the connecting arm 503. A slider 509 is slidably connected to the two sets of slide rods 508. A first spring 510 is provided between one side of the slider 509 and one end of the slide rod 508. A second motor 512 is mounted on the slider 509. The output shaft passes through the limiting hole 511 through the connecting arm 503 and protrudes outward. The end of the output shaft of the second motor 512 is provided with a roller 507. When the first motor 505 is started, it drives the second transmission gear 506 to rotate. The second transmission gear 506 drives the shaft 502 to rotate through the first transmission gear 504. The shaft 502 drives the connecting arm 503 to rotate around the shaft 502, causing the roller 507 to abut against the rotating rod 3. The connecting arm 503 continues to rotate, causing the slider 509 to slide along the slide rod 508, compressing the first spring 510. The elasticity of the first spring 510 can not only prevent the roller 507 from rigidly contacting the rotating rod 3 and causing damage to the tool, but also push the roller 507 to abut against the rotating rod 3.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, optionally, the base plate 1 is provided with a positioning mechanism 6 for fixing the tool to be inspected.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, optionally, the positioning mechanism 6 includes a side plate 601, which is disposed on the front of the base plate 1. A sleeve 602 is rotatably connected to the base plate 1, and a threaded rod 603 is screwed into the sleeve 602. A top plate 604 is fixedly connected to the top of the threaded rod 603. Vertical rods 605 are provided at the bottom of both ends of the top plate 604. The vertical rods 605 are slidably connected to the side plate 601 and penetrate downward through the side plate 601. A movable plate 606 is slidably connected to the vertical rod 605 and is slidably sleeved on the threaded rod 603. A limit block 9 is provided on the movable plate 606. A limit groove 8 that slides with the limit block 9 is provided on the vertical rod 605. A second spring 607 is sleeved on the vertical rod 605. One end of the second spring 607 is fixedly connected to the movable plate 606, and the other end is fixedly connected to the side plate 601. A first bevel gear is fixedly disposed on the sleeve 602. 608. A third motor 609 is installed on the base plate 1. A second bevel gear 610 that meshes with the first bevel gear 608 is installed on the output shaft of the third motor 609. A support arm 611 is installed on one side of the moving plate 606. A positioning wheel 612 is installed at the bottom of the support arm 611. When the third motor 609 is started, it drives the second bevel gear 610 to rotate. The second bevel gear 610 drives the sleeve 602 to rotate through the first bevel gear 608. The rotating sleeve 602 drives the threaded screw 603, the top plate 604 and the vertical rod 605 to move down. The second spring 607 in the stretched state will drive the moving plate 606 to move down, so that the positioning wheel 612 abuts against the top of the tool. The top plate 604 continues to move down so that the bottom of the top plate 604 contacts the top of the moving plate 606, ensuring that the elastic force of the second spring 607 can be fully applied to the tool through the positioning wheel 612 to fix the tool on the support frame 4.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, preferably, the base plate 1 is provided with a tool runout detection device 7 for detecting tool runout.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, a rubber pad is provided on the roller 507.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, the outside of the rotating rod 3 is provided with anti-slip texture; this increases the friction between the rotating rod 3 and the roller 507, thereby improving transmission efficiency.

[0039] In use, the tool is placed on the support frame 4. With the cooperation of the limiting block 9 and the limiting groove 8, the vertical rod 605 can drive the second spring 607 to stretch through the moving plate 606. The third motor 609 is started to drive the second bevel gear 610 to rotate. The second bevel gear 610 drives the sleeve 602 to rotate through the first bevel gear 608. The rotating sleeve 602 drives the threaded screw 603, the top plate 604 and the vertical rod 605 to move downward. The second spring 607 in the stretched state drives the moving plate 606 to move downward, so that the positioning wheel 612 abuts against the top of the tool. In order to avoid the bottom of the limiting groove 8 also providing support to the limiting block 9, so that the elastic force of the second spring 607 cannot act on the tool through the positioning wheel 612, the bottom of the top plate 604 is moved downward to contact the top of the moving plate 606, ensuring that the elastic force of the second spring 607 can act on the tool through the positioning wheel 612, so as to fix the tool on the support frame 4. The positioning wheel 612 can rotate with the tool. The moving tool rotates synchronously. The first motor 505 is started, driving the second transmission gear 506 to rotate. The second transmission gear 506 drives the shaft 502 to rotate through the first transmission gear 504. The shaft 502 drives the connecting arm 503 to rotate around the shaft 502, causing the roller 507 to abut against the rotating rod 3. The connecting arm 503 continues to rotate, causing the slider 509 to slide along the slide rod 508, compressing the first spring 510. The elasticity of the first spring 510 pushes the roller 507 to abut tightly against the rotating rod 3. The second motor 512 is started, driving the roller 507 to rotate. The roller 507 drives the rotating rod 3 to rotate. The rotating rod 3 drives the drive gear 408 to rotate through the connecting shaft 409. The drive gear 408 drives the first gear 404 and the second gear 407 to rotate synchronously, thereby driving the first belt 403 and the second belt 406 to rotate synchronously, so as to drive the tool to rotate at a constant speed. The tool runout detection device 7 is started to detect the tool rotating at a constant speed.

[0040] The tool runout detection platform provided by this invention, by setting a second spring 607, controls the moving plate 606 to move downward so that the positioning wheel 612 abuts against the top of the tool, and continues to move the top plate 604 downward so that the bottom of the top plate 604 contacts the top of the moving plate 606, ensuring that the elastic force of the second spring 607 can be fully applied to the tool through the positioning wheel 612, thus fixing the tool to the support frame 4, and thus fixing tools of different sizes to the support frame 4; starting the second motor 512 drives the roller 507 to rotate, the roller 507 drives the rotating rod 3 to rotate, the rotating rod 3 drives the drive gear 408 to rotate through the connecting shaft 409, the drive gear 408 drives the first gear 404 and the second gear 407 to rotate synchronously, thereby driving the first belt 403 and the second belt 406 to rotate synchronously, so as to drive tools of different sizes to rotate at a uniform speed.
