Description

Technical Field

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding. Molds are common components of grinder processing. Molds need to be clamped before grinding. The choice of clamping tools plays a vital role in the entire grinding process. Therefore, before grinding the mold, it must be positioned and clamped on the workbench.

[0003] Prior art, such as Chinese patent publication number CN219170580U, discloses a mold positioning and clamping device, including a support plate and a square frame plate, wherein the support plate is detachably embedded with a plurality of guide columns, each guide column is slidably sleeved with a slider, a clamp is connected to the top of a plurality of sliders close to the same side wall of the square frame plate, an end of the clamp away from the center of the support plate is connected to a scale column, the scale column laterally penetrates the square frame plate, a screw rod is rotatably connected to the center of the bottom end of the support plate, a slip ring is provided on the longitudinal sliding sleeve of the screw rod, an inclined rod is rotatably connected between a plurality of sliders at the bottom end of the same clamp, and the other end of the inclined rod is rotatably connected to the slip ring, the utility model drives the slip ring to slide downward along the longitudinal direction of the screw rod to drive one end of the inclined rod to slide synchronously, and then drives the slider to slide along the guide column laterally toward the center of the support plate through the pulling of the inclined rod until the clamp abuts against the side walls around the mold to complete the clamping, thereby ensuring that the plurality of clamps slide synchronously toward the side walls around the mold.

[0004] In order to solve the problem that the mold clamping device cannot clamp firmly, especially for special-shaped molds, it is easy to appear to be clamped but is actually only partially clamped. Once the processing starts, accidents are likely to occur, so improvements are needed. Utility Model Content

[0024] The specific arrangement and function of the clamping mechanism 5 and the adjusting mechanism 6 will be described in detail below.

[0025] In this embodiment: the clamping mechanism 5 includes a first motor 501, the first motor 501 is fixedly connected to the inner wall of the workbench 3, the number of the first motors 501 is two groups, the surface of the first motors 501 is fixedly connected with a first electric hydraulic push rod 502, and the surface of the first electric hydraulic push rod 502 is fixedly connected with a connecting block 503.

[0026] The effects achieved by the above components are as follows: after the first motor 501 is started, the first electric hydraulic push rod 502 drives the connecting block 503 to move in the horizontal direction.

[0027] Specifically, a rack rod 504 is fixedly connected to the surface of the connecting block 503, a large gear 505 is meshingly connected to the surface of the rack rod 504, a connecting column 506 is fixedly connected to the surface of the large gear 505, a rotating disk 507 is fixedly connected to the surface of the connecting column 506, an anti-slip disk 508 is fixedly connected to the surface of the rotating disk 507, an anti-slip pad 510 is fixedly connected to the surface of the anti-slip disk 508, and a through hole 511 is opened on the surface of the workbench 3.

[0028] The effect achieved by the above components is: the connecting block 503 drives the rack rod 504 to move horizontally, and then the rack rod 504 drives the large gear 505 to rotate, thereby driving the connecting column 506, the rotating disk 507, the anti-slip disk 508 and the anti-slip pad 510 to rotate in the through hole 511.

A first rotating groove 604 is opened on the surface of the fixed platform 601, and the number of the first rotating grooves 604 is two groups. The surfaces of the first rotating grooves 604 are all fixedly connected to a first rotating shaft 605.

[0035] Specifically, a second rotating groove 606 is formed on the surface of the workbench 3 , and a second rotating shaft 607 is fixedly connected to the surface of the second rotating groove 606 ; a third rotating groove 608 is formed on the surface of the leg 2 , and a third rotating shaft 609 is fixedly connected to the surface of the third rotating groove 608 .

[0036] The effects achieved by the above components are: the second rotation groove 606 and the second rotation axis 607 are used to convert the horizontal thrust of the second electric hydraulic push rod 603 into rotational motion, and the third rotation groove 608 and the third rotation axis 609 serve as the axis of rotation of the adjustment mechanism 6.

[0038] The effects achieved by the above components are: after the second motor 602 is started, the second electric hydraulic push rod 603 applies an oblique upward thrust and is converted into a rotational motion with the third rotation axis 609 as the axis, so that the workbench 3 is tilted at a certain angle.

[0039] Working principle: By setting the clamping mechanism 5, when the motor is turned on, it drives the first electric hydraulic push rod 502, and then drives the connecting block 503 to make the rack rod 504 move in the horizontal direction. The rack rod 504 engages with the transmission gear 505 to rotate the connecting column 506, and then drives the rotation of the rotating disk 507 and the anti-skid pad 510. At the same time, the rack rod 504 also engages with the transmission pinion 512 to rotate the bidirectional threaded rod 513. The movable block 514 thus moves horizontally on the bidirectional threaded rod 513, and then drives the clamping plate 4 to move toward or away from each other. By setting the clamping mechanism 5, when positioning and clamping the mold, in addition to clamping the mold from four horizontal directions, the mold can also be rotated in situ, and the in situ rotation and horizontal displacement occur synchronously. The clamping mechanism 5 can find the most suitable angle and distance for the strongest clamping, which effectively improves the usability of the clamping device. In addition, by setting the adjustment mechanism 6, when the motor is turned on, it drives the second electric push rod, which in turn enables the second electric push rod to give the workbench 3 an oblique upward thrust. Under the action of the second rotating axis 607 and the third rotating axis 609, the oblique upward thrust will be converted into a rotational motion with the third rotating axis 609 as the axis, and the setting of the first rotating axis 605 enables the electric hydraulic push rod to rotate to a certain extent, so that the rotation angle of the workbench 3 is larger. By setting the adjustment mechanism 6, the side of the mold can be processed without removing the mold, and there is a larger selection space for the processing angle, which effectively improves the convenience of the clamping device.
