[0024] Example 1:
[0025] As attached Figure 1 To be continued Figure 4 As shown:
[0026] This utility model provides an adjustable machine tool support pad, including a housing 1 for accommodating and protecting the internal structure. Inside the housing 1 is a lifting assembly 2 for raising the height of the machine tool support. A first pad 3, located on the lifting assembly 2, is slidably disposed within the housing 1. The first pad 3 penetrates the upper end of the housing 1 and extends to the outside of the housing 1, supporting the machine tool support. The first pad 3 has placement holes 4 for placing the machine tool support. Multiple sliding grooves 5 are located beside the placement holes 4 on the first pad 3. Sliding blocks 6 are rotatably disposed within the sliding grooves 5. A cavity 7, located below the sliding blocks 6 and communicating with the placement holes 4, is formed on the first pad 3. A transmission mechanism 8 is slidably disposed within the cavity 7. The multiple sliding blocks 6 move synchronously through the transmission mechanism 8, synchronously retracting inward to clamp the machine tool support. Different retraction distances can clamp machine tool supports of different sizes.
[0027] The transmission mechanism 8 includes a turntable 801, which is slidably disposed in the cavity 7. One side of the turntable 801 is provided with helical teeth 802. An arc-shaped groove 9 is opened at the bottom of the slider 6. The helical teeth 802 on the turntable 801 mesh with the arc-shaped groove 9 at the bottom of the slider 6. When the turntable 801 rotates, the helical teeth 802 rotates accordingly. Since the arc-shaped groove 9 is always meshed with the helical teeth 802, the slider 6 can only move forward or backward along the groove 5.
[0028] Multiple movable holes 10 are opened in the first pad 3, and a bevel gear 804 is rotatably installed in each movable hole 10. A rack 803 is provided on the bottom surface of the turntable 801. The rack 803 meshes with the bevel gear 804. The bevel gear 804 drives the turntable 801 to rotate. The multiple bevel gears 804 meshing with the rack 803 of the turntable 801 can make the turntable 801 rotate smoothly in the cavity 7.
[0029] One of the bevel gears 804 is connected to an operating lever 11. The operating lever 11 extends to the outside of the first pad 3 and is connected to a knob. It extends out of the first pad 3 for easy use by the operator. The operator only needs to rotate the operating lever 11 to drive one bevel gear 804 to rotate, so that multiple sliders 6 can move synchronously.
[0030] The slider 6 is provided with a gripper 13 near the placement hole 4. The gripper 13 is used to increase the contact area with the machine tool support, making the whole mechanism more stable. A shim 14 is provided on the gripper 13. The shim 14 is placed between the machine tool support and the gripper 13 to increase the friction, make the gripper 13 grip more firmly, and protect the machine tool support and the gripper 13 to avoid wear caused by vibration and friction during machine tool operation.
[0031] The slider 6 and the gripper 13 are connected by a disassembly structure 12. The gripper 13 is detachable and replaceable. The gripper 13 can be set as an arc-shaped gripper or a straight gripper to adapt to different shapes of machine tool feet. The disassembly structure 12 includes a connecting block 1201 set on the slider 6. A notch 1202 is opened in the connecting block 1201. A meshing piece 1203 corresponding to the notch 1202 is set on the gripper 13. The connecting block 1201 and the meshing piece 1203 are threadedly connected by a screw 1204. The meshing piece 1203 and the notch 1202 cooperate to make the direction of each gripper 13 uniform, which is convenient for gripping the machine tool feet.
[0032] The lifting assembly 2 includes a first pad 3 and a second pad 201 that slide inside the outer casing 1. The first pad 3 has a groove in its middle to accommodate a portion of the second pad 201. This groove allows a portion of the second pad 201 to slide into the lower end of the first pad 3, reducing the overall size of the device. The bottoms of the second pad 201 and the third pad 202 are respectively threaded with threaded rods 203. The threaded rods 203 penetrate the side wall of the outer casing 1 and extend to the outside of the outer casing 1. The threaded sections in the second pad 201 and the third pad 202 rotate in opposite directions. When the threaded rods 203 are rotated, they cause the second pad 201 and the third pad 202 to move synchronously in opposite directions. Since both the second pad 201 and the third pad 202 are wedge-shaped blocks, the first pad 3 moves up and down along the inclined surfaces of the second pad 201 and the third pad 202, allowing the height of the first pad 3 to be adjusted as needed.
[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
