Description

Technical Field

[0001] The present invention relates to the field of machine tool assembly, in particular to a manual flipping device for scraping the base of a machine tool. Background Art

[0002] Grinding is one of the important means to improve the accuracy and stability of machine tools. Through grinding, the surfaces of two parts with an assembly relationship can be made smoother, and the joint surfaces can be in closer contact, thus ensuring more stable machine tool accuracy. Grinding treatment is required between the base of the machine tool and the machine tool guide rail. During grinding, the base of the machine tool needs to reciprocate frequently on the guide rail, and the workload is very large. Especially when the volume and weight of the machine tool base are relatively large, large lifting tools such as cranes are needed for handling. At the same time, during the grinding process, the machine tool base needs to be tilted at a certain angle, and then manual scraping is carried out. After the scraping operation, the machine tool base is driven to cooperate with the machine tool guide rail again. This method is time-consuming and laborious, requires a large amount of manual labor, and has relatively low work efficiency. Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0017] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings. As Figures 1 to 5 shown: A manual turning device for scraping a machine tool base, the device includes a vehicle body 1 as a base, a support column 2 is arranged on the vehicle body 1, a support frame 3 is arranged at the top of the support column 2, and handrails 4 are arranged at both the front and rear ends of the support frame 3.

[0018] Both sides of the support frame 3 are respectively connected to both sides of a bearing bracket 5 through a set of pulley mechanisms. A support plate 6 and a limit frame 7 perpendicular to each other are arranged on the bearing bracket 5. A rubber stop 8 is arranged on the limit frame 7. A movable pulley support 9 is arranged on the bearing bracket 5. A movable pulley 10 is rotatably supported on the movable pulley support 9. Mounting plates 11 are symmetrically arranged on both sides of the bearing bracket 5. A central wheel 12 is arranged on the mounting plate 11. Front rollers 13 and rear rollers 14 are respectively arranged on the mounting plate 11 on both sides of the central wheel 12.

[0019] A slideway is arranged inside the support column 2. The central wheel 12 is in rolling connection with the slideway. A guide block 15 is also arranged on the side of the support column 2, and the guide block 15 is matched with the front roller 13.

[0020] The pulley mechanism includes a first fixed pulley 16, a second fixed pulley 17 and a fixed point 18 arranged on the support frame 3. One end of a connecting rope 19 is connected to the fixed point 18. The other end of the connecting rope 19 is sequentially wound around the movable pulley 10, the first fixed pulley 16 and the second fixed pulley 17, and then connected to a counterweight 21 through a connecting hook 20.

[0021] A support piece 24 is arranged on the support column 2. An upper limit bolt 25 is arranged on the support piece 24. Two nuts 26 are respectively threadedly connected to the upper and lower end faces of the support piece 24 on the upper limit bolt 25, and the upper limit bolt 25 is located above the movable pulley support 9.

[0022] A lower limit bolt 27 is arranged on the movable pulley support 9. Two nuts 26 are respectively threadedly connected to the upper and lower end faces of the movable pulley support 9 on the lower limit bolt 27. A receiving hole is opened on the support column 2. A limit shaft 28 is movably inserted into the receiving hole, and the limit shaft 28 is matched with the bottom end of the lower limit bolt 27.

[0023] The working process of the manual flipping device for scraping the machine tool base in the embodiment of the present invention is as follows: First, select a suitable counterweight 21 according to the mass of the machine tool base 22 to be processed, so as to ensure that after the machine tool base 22 is placed on the bearing bracket 5, the counterweight 21 can roughly offset the mass of the machine tool base 22, so that the operator does not need to consume too much force when driving the bearing bracket 5 to move;

[0024] In the initial state, the bearing bracket 5 is at the top of the support column 2 and is locked under the action of the locking mechanism. At this time, the pallet 6 on the bearing bracket 5 is horizontally distributed. Place the machine tool base 22 on the pallet 6. At this time, the pallet 6 is at the same height as the plane where the machine tool guide rail 23 is located. The operator aligns the machine tool base 22 on the pallet 6 with the machine tool guide rail 23 and pushes it onto the machine tool guide rail 23. Push and pull the machine tool base 22 back and forth to make it rub against the machine tool guide rail 23 to achieve grinding. After grinding for a period of time, pull the machine tool base 22 back onto the pallet 6. The machine tool base 22 is separated from the machine tool guide rail 23, and then manually flip the machine tool base 22 so that the bottom surface faces up. Then press down the bearing bracket 5, and the entire bearing bracket 5 moves downward along the support column 2. During the movement, the central wheel 12 rolls in the slideway in the support column 2. When the front roller 13 moves to the guide block 15, it will move along the contour of the guide block 15. This movement of the front roller 13 will change the overall posture of the bearing bracket 5, causing the bearing bracket 5 to move downward while swinging counterclockwise with the central wheel 12 as the pivot until the rear roller 14 contacts the side wall of the support column 2. That is to say, when the bearing bracket 5 moves downward to the position of the guide block 15, it will swing (i.e., change from the state in Figure 1 to the state in Figure 2 ). At this time, the side wall of the machine tool base 22 contacts the rubber stopper 8 provided on the limit frame 7, and the bottom surface still contacts the pallet 6. That is, the pallet 6 and the limit frame 7 jointly support the machine tool base 22, and a certain angle is formed between the machine tool base 22 and the horizontal plane.

[0025] In this state, observe the grinding marks in the chute on the machine tool base 22. If the number of contact points per unit area meets the requirements, it means that the grinding is completed. Otherwise, manual scraping is required. Since the machine tool base 22 is inclined at this time, this posture and angle are more conducive to the operator's scraping operation;

[0026] After scraping, lift the bearing bracket 5 again to restore it to its initial position and posture. After flipping the machine tool base 22 again, push it onto the machine tool guide rail 23 again and move it back and forth again. Repeat this process until the chute on the machine tool base 22 meets the scraping requirements;

[0027] The connecting rope 19 wound around the movable pulley 10 exerts an upward force on the movable pulley 10. That is to say, the bearing bracket 5 is supported by the connecting rope 19. When the bearing bracket 5 is pressed down, the bearing bracket 5 and the movable pulley 10 move downward, and the other end of the connecting rope 19 drives the connecting hook 20 and the counterweight 21 to move upward. During this process, the counterweight 21 is used to balance the weight of the bearing bracket 5 (and the machine tool base 22 thereon), and the operator can easily drive the bearing bracket 5 to move;

[0028] When the bearing bracket 5 has reached the same height as the machine tool guide rail 23, it is necessary to lock the bearing bracket 5 using the locking device. The locking device includes an upper limit bolt 25 and a lower limit bolt 27. Adjust the upper limit bolt 25 to contact the top surface of the movable pulley support 9, and then use the nut 26 to lock the upper limit bolt 25 on the support plate 24. Pull the limit shaft 28 out of the accommodation hole, let the limit shaft 28 move below the lower limit bolt 27, then adjust the lower limit bolt 27 to contact the limit shaft 28, and then use the nut 26 to lock the lower limit bolt 27 on the movable pulley support 9, thus completing the locking operation of the bearing bracket 5;

[0029] After unlocking the locking device, the bearing bracket 5 regains its freedom of movement, and the operator can drive it to move longitudinally.
