Description

Technical Field

[0001] The present application relates to the technical field of handwheels, and in particular to a handwheel casting for a CNC machine tool. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by casting, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] Handwheel casting is a common casting and is often used on CNC machine tools. Modern handwheel castings are mostly made up of an inner ring, a connector and an outer ring. Traditional handwheels sometimes have a fixing rod welded on the outside to save effort. This is to increase the torque radius of the handwheel and save effort. However, welding the fixing rod will increase the space occupied by the handwheel, which has a great impact on other operations in actual use. Utility Model Content

[0004] In order to improve the existing method of handwheel casting, in which the torque radius is increased by welding a fixing rod, so that the user can turn the handwheel more labor-saving, but the handwheel occupies more space after welding the fixing rod, which is inconvenient for the user to use, the present application provides a CNC machine tool handwheel casting.

[0005] The present application provides a CNC machine tool handwheel casting, which adopts the following technical solution:

[0006] A CNC machine tool handwheel casting comprises an inner ring, an outer ring concentric with the inner ring is sleeved on the outer side of the inner ring, a plurality of equally spaced connecting pieces are arranged between the inner ring and the outer ring, the inner ring is connected to the outer ring through the connecting pieces, the inner ring, the outer ring and the connecting pieces are integrally formed by casting a metal solution, a receiving groove penetrating the outer ring is reserved in the middle of the connecting piece, connecting blocks are fixedly connected to the outer rings on both sides of the receiving groove, a power-assisting pipe is rotatably connected between the two connecting blocks, and the size of the power-assisting pipe is adapted to the size of the inner cavity of the receiving groove.

[0007] By adopting the above technical solution, when using, the user first installs the inner ring on the CNC machine tool. When in use, the user can rotate the outer ring, drive the inner ring to rotate synchronously through the connecting piece, and adjust the CNC machine tool. When the user has difficulty rotating the outer ring due to insufficient torque of the outer ring, the user can flip the power-assisting tube outward 180 degrees, and turn the power-assisting tube out of the inner cavity of the accommodating groove. Then, the user holds the end of the power-assisting tube away from the outer ring and pushes the outer ring to rotate. By increasing the torque, the user can save effort when rotating the outer ring. When the adjustment is completed, the user can rotate the power-assisting tube in the opposite direction, and re-embed the power-assisting tube into the inner cavity of the accommodating groove to store the power-assisting tube. This avoids the problem that the existing handwheel casting increases the torque radius by welding the fixing rod, which makes it easier for the user to turn the handwheel. However, after welding the fixing rod, the handwheel occupies more space, which is inconvenient for the user to use.

[0008] Optionally, a connecting hole is opened at the center of the inner ring, and the inner ring is connected to the rotating shaft of the CNC machine tool through the connecting hole.

[0009] By adopting the above technical solution, the diameter of the connecting hole is the same as the diameter of the rotating shaft of the CNC machine tool, so that the user can put the inner ring on the rotating shaft through the connecting hole and weld it to install the handwheel on the CNC machine tool.

[0010] Optionally, the outer circumferential side is provided with spiral anti-slip grooves.

[0011] By adopting the above technical solution, anti-slip grooves are provided on the shaft side of the outer ring to increase the friction between the outer ring and the palm of the user, thereby avoiding relative sliding between the palm of the user and the outer ring when the outer ring is rotated.

[0012] Optionally, a connecting shaft is passed through the end of the power-assisting pipe, both ends of the connecting shaft pass through the connecting block and are rotatably connected to the connecting block, and a bearing is installed at the connection between the connecting shaft and the connecting block.

[0013] By adopting the above technical solution, a connecting shaft is provided to rotatably connect one end of the power-assisting pipe to the connecting block, and a bearing is provided to reduce the friction between the connecting shaft and the connecting block.

[0014] Optionally, a boost rod is slidably connected in the inner cavity of the free end of the boost tube, and a limit bolt is provided at the connection between the boost tube and the boost rod. The limit bolt passes through the boost tube and is threadedly connected to the boost tube. One end of the limit bolt located in the inner cavity of the boost tube abuts against the boost rod.

[0015] By adopting the above technical solution, when the user needs greater force to rotate the outer ring, the power-assisting rod can be stretched outward to increase the torque when rotating the handwheel, which is convenient for the user. After the power-assisting rod is slid to the appropriate position, the limit bolt can be screwed to relatively fix the power-assisting tube and the power-assisting rod.

[0016] Optionally, a magnetic column is fixedly connected to one end of the boosting rod located outside the boosting tube, and an accommodating hole with an inner cavity matched to the size of the magnetic column is opened at one end of the accommodating groove close to the inner ring.

[0017] By adopting the above technical solution, when the user is not in use, the power-assisting tube can be rotated so that the power-assisting tube is accommodated in the inner cavity of the accommodating groove, and then the power-assisting rod can be fixed by the magnetic column under the action of the magnetic field force to prevent the power-assisting tube from shaking from the inner cavity of the accommodating groove.

[0018] Optionally, widening grooves are provided on the side walls on both sides of the middle section of the accommodating groove, and a gap is left between the inner wall of the widening groove and the outer wall of the power-assisting pipe.

[0019] By adopting the above technical solution, it is convenient for the user to insert his fingers into the inner cavity of the widening groove and take the power-assisting tube out of the inner cavity of the accommodating groove for use.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] 1. The present application adopts the coordination arrangement among the structures such as the connecting piece, the accommodating groove, the connecting block, the power-assisting tube and the connecting shaft. When in use, the user can rotate the power-assisting tube to rotate it out of the inner cavity of the accommodating groove to increase the torque, making it easier for the user to rotate the handwheel. After use, the power-assisting tube can be rotated in the opposite direction and re-embedded into the inner cavity of the accommodating groove to store the power-assisting tube. This avoids the problem that the existing handwheel casting increases the torque radius by welding the fixing rod, making it easier for the user to turn the handwheel. However, after welding the fixing rod, the space occupied by the handwheel increases, which is inconvenient for the user to use.

[0022] 2. By slidingly connecting the power-assisting rod in the inner cavity of the free end of the power-assisting tube and installing a limit bolt at the connection between the power-assisting tube and the power-assisting rod, the user can slide the power-assisting rod outward along the length direction of the power-assisting tube when in use, thereby increasing the length of the overall power-assisting structure, thereby increasing the torque again, making it more labor-saving for the user to use. After use, the user can slide the power-assisting rod into the power-assisting tube, hide the power-assisting rod inside the power-assisting tube, and fix it with a limit bolt, thereby reducing the space occupied by the power-assisting structure.

[0029] A plurality of equally spaced connectors 5 are provided between the inner ring 1 and the outer ring 3. The inner ring 1 is connected to the outer ring 3 via the connectors 5. The inner ring 1, the outer ring 3 and the connectors 5 are integrally formed by casting metal solution.

[0030] A receiving groove 6 penetrating the outer ring 3 is reserved in the middle of the connecting member 5, and connecting blocks 7 are fixedly connected to the outer ring 3 on both sides of the receiving groove 6. A boosting pipe 8 is rotatably connected between the two connecting blocks 7, and the size of the boosting pipe 8 is adapted to the size of the inner cavity of the receiving groove 6.

[0031] Reference Figure 1 A connecting hole 2 is provided at the center of the inner ring 1, and the inner ring 1 is connected to the rotating shaft of the CNC machine tool through the connecting hole 2. The hole diameter of the connecting hole 2 is the same as the diameter of the rotating shaft of the CNC machine tool, so that the user can sleeve the inner ring 1 on the rotating shaft through the connecting hole 2 and weld it, and then install the handwheel on the CNC machine tool.

[0032] Reference Figure 1 The outer ring 3 is provided with a spiral anti-skid pattern 4 on its circumference. The anti-skid pattern 4 is provided on the axial side of the outer ring 3 to increase the friction between the outer ring 3 and the palm of the user, and to avoid relative sliding between the palm and the outer ring 3 when the user rotates the outer ring 3.

[0033] Reference Figure 2 and Figure 3 The end of the power-assisting tube 8 is penetrated by a connecting shaft 9, both ends of the connecting shaft 9 pass through the connecting block 7 and are rotatably connected to the connecting block 7, and a bearing 10 is installed at the connection between the connecting shaft 9 and the connecting block 7. The connecting shaft 9 is provided for rotatably connecting one end of the power-assisting tube 8 to the connecting block 7, and the bearing 10 is provided for reducing the friction between the connecting shaft 9 and the connecting block 7.

[0034] Reference Figure 3A boost rod 11 is slidably connected in the inner cavity of the free end of the boost tube 8, and a stop bolt 12 is provided at the connection between the boost tube 8 and the boost rod 11. The stop bolt 12 penetrates the boost tube 8 and is screwed with the boost tube 8. One end of the stop bolt 12 located in the inner cavity of the boost tube 8 abuts against the boost rod 11. When the user needs greater strength to rotate the outer ring 3, the boost rod 11 can be stretched outward to increase the torque when rotating the hand wheel, which is convenient for the user to use. After the boost rod 11 is slid to a suitable position, the stop bolt 12 can be screwed to relatively fix the boost tube 8 and the boost rod 11.

[0035] Reference Figure 1 and Figure 3 The end of the booster rod 11 outside the booster tube 8 is fixedly connected with a magnetic column 13, and the end of the receiving groove 6 close to the inner ring 1 is provided with a receiving hole 14 whose inner cavity is adapted to the size of the magnetic column 13.

[0037] The implementation principle of the present application is: when in use, the user first installs the inner ring 1 on the CNC machine tool. When in use, the user can rotate the outer ring 3, drive the inner ring 1 to rotate synchronously through the connecting piece 5, and adjust the CNC machine tool. When the torque of the outer ring 3 is insufficient, which makes it difficult for the user to rotate the outer ring 3, the user can flip the power-assisting tube 8 outward one hundred and eighty degrees, and turn the power-assisting tube 8 out of the inner cavity of the accommodating groove 6. Then, the user holds the end of the power-assisting tube 8 away from the outer ring 3 to push the outer ring 3 to rotate, and the torque is increased to make it easier for the user to rotate the outer ring 3. When the adjustment is completed, the user can rotate the power-assisting tube 8 in the opposite direction, and re-embed the power-assisting tube 8 into the inner cavity of the accommodating groove 6 to store the power-assisting tube 8. This avoids the problem that the existing handwheel casting increases the torque radius by welding the fixing rod, which makes it easier for the user to turn the handwheel. However, after welding the fixing rod, the handwheel occupies more space, which is inconvenient for the user to use.
