Specifically speaking, be fixed with the square column between the roof both sides of frame and the bottom plate both sides respectively, the ejector pin subassembly includes the connecting plate, the connecting plate both sides are fixed with the rectangular pipe respectively, the ejector pin is fixed at connecting plate bottom surface center, rectangular pipe and square column sliding fit.
Furthermore, L-shaped clamping blocks are respectively fixed on the frame bottom plates on two sides of the open slot, and the cushion block is clamped between the L-shaped clamping blocks.
And handles convenient for drawing operation are respectively welded and fixed on two sides of the upper end of the frame.
The utility model has the advantages that: the utility model discloses a lifting screw promotes the ejector pin subassembly and moves down, utilizes ejector pin roof pressure motor shaft cooperation cushion to pull out gear or bearing on with the motor shaft, need not to use the hammer to strike, not only can avoid the damage of gear, bearing and motor shaft, can also avoid operation in-process personnel injured, overall structure is simple, convenient to use.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the state of the gear drawing device of the present invention.
In the figure: 1. the lifting device comprises a frame, a top plate 1-1, a bottom plate 1-2, a square column 1-3, a reinforcing rib plate 1-4, an open slot 1-5, a lifting screw 2, a push rod assembly 3, a connecting plate 3-1, a rectangular tube 3-3, a push rod 4, a cushion block 4-1, an open arc slot 4-1, a handle 5, a 6.L-shaped clamping block and a gear 7.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the drawing tool used for both the motor and the gear bearing includes a frame 1, a lifting screw 2, a ram assembly 3, and a spacer 4.
Frame 1: the square column drawing device comprises a top plate 1-1 and a bottom plate 1-2, square columns 1-3 are respectively fixed between two sides of the top plate 1-1 and two sides of the bottom plate 1-2, reinforcing rib plates 1-4 are fixedly connected between the inner sides of the upper ends of the square columns 1-3 and the bottom surface of the top plate 1-1 and between the inner sides of the lower ends of the square columns 1-3 and the surface of the bottom plate 1-2, handles 5 convenient for drawing operation are respectively fixed on the outer side surfaces of the upper ends of the two square columns 1-3, an open slot 1-5 with a forward opening is arranged at the center of the bottom plate 1-2, inverted L-shaped clamping blocks 6 are respectively fixed on the bottom plates 1-2 at two sides of the open slot 1-5, and the short sides of the two L-shaped clamping blocks 6 are opposite.
The lifting screw 2 is in threaded connection with the center of the top plate 1-1 of the frame 1, and a square hole which can be connected with a square shaft at the head of the electric wrench is formed in the top of the lifting screw 2.
The ejector rod component 3 is arranged in the frame 1 in a sliding mode, the ejector rod component 3 comprises a connecting plate 3-1, rectangular pipes 3-2 are fixed to two sides of the connecting plate 3-1 respectively, an ejector rod 3-3 is fixed to the center of the bottom face of the connecting plate 3-1, the rectangular pipes 3-2 are in sliding fit with square columns 1-3 of the frame 1, and the bottom end of the lifting screw rod 2 is pressed against the upper end face of the connecting plate 3-1.
As shown in figure 2, when the gear box is pulled, a motor shaft passes through the open arc groove 4-1 to enable a gear 7 or a bearing to be pulled to be arranged on the upper surface of the cushion block 4, then the motor shaft passes through an open groove 1-5 on a bottom plate 1-2 to clamp and press the cushion block 4 between the two L-shaped clamp blocks 6, a push rod assembly 3 moves upwards to enable a push rod 3-3 to be pressed on the end face of the motor shaft, the head of an electric wrench is connected with a lifting screw 2, the electric wrench is started to drive the lifting screw 2 to rotate and descend to push the push rod assembly 3 to move downwards, the push rod 3-3 pushes the motor shaft to move downwards, and the cushion block 4 drives the gear 7 or the bearing to pull upwards, so that the gear 7 or the bearing is pulled out of the motor shaft. The drawing tool is simple in overall structure, convenient to use, safe, reliable and not prone to damage of a motor shaft.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
