Description

Technical Field

[0001] This utility model relates to the technical field of connection conversion devices, and in particular to connection conversion devices suitable for machining lathe spindles of different specifications. Background Technology

[0002] The lathe spindle connection conversion device is a core transitional component that connects the lathe spindle with the tool or workpiece clamping assembly (such as chuck, center, tool holder). Its core function is to realize the "spindle power and speed transmission" and the "clamping mode switching under different machining requirements", while ensuring the coaxiality, rigidity and transmission stability of the spindle and the clamping assembly, which directly affects the machining accuracy (such as roundness and cylindricity) and cutting efficiency of the lathe.

[0003] Existing lathe spindle connection conversion devices have a single installation method. For example, the spindle connection methods of the CD6140A CNC lathe and the GLS-200 CNC lathe are different. The spindle of the CD6140A CNC lathe has a tapered positioning structure, while the spindle of the GLS-200 CNC lathe has a stop positioning structure. This means that the tooling that is normally used on the CD6140A CNC lathe cannot be used on the GLS-200 CNC lathe. Since there are many models of old tooling, redesigning new tooling suitable for the GLS-200 CNC lathe would be a huge investment and would not meet the needs of lean production. Therefore, there is an urgent need to design a spindle connection conversion device suitable for different specifications of lathes. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing lathe spindle connection conversion device cannot simultaneously adapt to the connection of new and old models of tooling.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a connection conversion device suitable for machining lathe spindles of different specifications, including: a first machine tool spindle connecting plate and a second machine tool spindle connecting plate, the first machine tool spindle connecting plate and the second machine tool spindle connecting plate are connected by a positioning stop and tightened by a hexagonal head screw; an intermediate connecting plate, the intermediate connecting plate is placed between the first machine tool spindle connecting plate and the second machine tool spindle connecting plate; a packing bolt, the packing bolt is placed inside the hole of the second machine tool spindle connecting plate, wherein the packing bolt is always in the waist-shaped hole of the intermediate connecting plate due to inertia, so as to achieve the connection and fastening effect.

[0006] The effect achieved by the above components is as follows: When using this connection conversion device, the GLS-first machine tool spindle connecting plate and the CDA second machine tool spindle connecting plate are connected through the positioning stop and tightened by MX socket head cap screws. The intermediate connecting disc is pre-placed between the first machine tool spindle connecting plate and the second machine tool spindle connecting plate. Note that its placement direction must be as shown in the figure. Then, the connection conversion device assembly after tightening the MX socket head cap screws can be connected to the GLS-CNC lathe spindle through the stop. Then, by rotating the intermediate connecting disc and tightening it with the packing bolts and nuts, all old water pump bodies and water pipes suitable for CDA CNC lathe tooling can be connected to the GLS-CNC lathe through this connection conversion device. This allows all models of old tooling to be installed on the newly added GLS-CNC lathe in the workshop without any modification.

[0007] Preferably, the device further includes: a lubrication device disposed on the second machine tool spindle connecting plate, the lubrication device comprising: a slot formed on the second machine tool spindle connecting plate, wherein the slot corresponds to the position of the oblong hole on the intermediate connecting plate; an oil reservoir inserted into the slot, wherein the oil reservoir is placed inside the slot and fixed by screws, wherein the oil reservoir is filled with lubricating grease; a concave frame fixed to the side of the oil reservoir near the intermediate connecting plate, wherein a rectangular hole is formed between the concave frame and the oil reservoir; and a rubber roller rotatably mounted on the concave frame via bearings, wherein the surface of the rubber roller is in contact with the surface of the intermediate connecting plate, wherein a portion of the rubber roller is placed inside the rectangular hole and the oil reservoir and in contact with the lubricating grease.

[0008] The effects achieved by the above components are as follows: By setting up a lubrication device, the oil reservoir is first manually inserted into the slot and fixed with screws, so that the oil reservoir is fixedly mounted on the second machine tool spindle connecting plate, making the surface of the rubber roller fit against the surface of the intermediate connecting disc. When the intermediate connecting disc rotates, it causes the rubber roller to rotate inside the concave frame and the oil reservoir, so that the rubber roller comes into contact with the lubricating grease inside the oil reservoir during rotation, allowing the lubricating grease to adhere to the surface of the rubber roller and be applied to the intermediate connecting disc during subsequent rotation of the rubber roller, thereby completing the auxiliary lubrication of the intermediate connecting disc, reducing the situation where the intermediate connecting disc lacks lubricating oil, which would lead to increased friction between the intermediate connecting disc and the second machine tool spindle connecting plate and the packing bolts, affecting the service life of the intermediate connecting disc. At the same time, the intermediate connecting disc can be automatically lubricated by the operator while rotating it, improving the convenience of lubrication.

[0009] Preferably, two guide plates are symmetrically fixed to the inner wall of the oil storage box on the side near the rubber roller, wherein the guide plates are triangular in shape.

[0010] The effect achieved by the above components is that by setting the guide plate, the lubricating grease inside the oil reservoir can be guided by the slope of the guide plate surface to flow towards the center of the oil reservoir, reducing the occurrence of some lubricating grease residue inside the oil reservoir.

[0011] Preferably, an auxiliary plate is fixed to one side of the oil storage box, wherein the auxiliary plate is rectangular in shape.

[0012] The effect achieved by the above components is that by setting up the auxiliary plate, a point of leverage can be provided for personnel to manually pull out the oil reservoir, reducing the chance of slipping when manually pulling out the oil reservoir.

[0013] Preferably, an injection pipe is fixedly connected to one side of the oil storage box, wherein the injection pipe is placed inside the oil storage box and does not fit against the inner wall of the oil storage box, and a sealing cap is threaded to the end of the injection pipe placed outside the oil storage box.

[0014] The effect achieved by the above-mentioned components is that by setting up the injection pipe, personnel can directly inject lubricating grease into the oil storage box through the injection pipe, making it convenient for personnel to replenish the oil in the oil storage box.

[0015] Preferably, a rubber plug is fixed to the inner wall of the sealing cap, wherein the size and shape of the rubber plug are adapted to the size and shape of the inner wall of the oil injection pipe, and the rubber plug is placed inside the injection pipe to completely seal its interior.

[0016] The effect achieved by the above components is as follows: by setting the rubber plug, the rubber plug can be inserted into the oil injection pipe to completely seal its interior, preventing the lubricating grease inside the oil reservoir from entering the oil injection pipe and causing blockage, thus affecting subsequent normal oil injection.

[0017] Preferably, the surface of the sealing cover is fixed with a plurality of anti-slip strips, and the plurality of anti-slip strips are arranged at equal intervals.

[0018] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the surface of the sealing cover can be increased, reducing the chance of slipping when manually turning the sealing cover.

[0019] Preferably, a spring rod is slidably connected to the inner wall of the hole of the oil storage box, wherein the other end of the spring in the spring rod is fixedly connected to the oil storage box, and a piston plate is fixedly connected to one end of the spring rod inside the oil storage box.

[0020] The effect achieved by the above components is as follows: by setting the piston plate, under the reaction force of the spring in the spring rod, the spring rod always keeps pushing the piston plate, so that after the piston plate is pushed, it pushes the lubricating grease inside the oil reservoir towards the rubber roller, reducing the occurrence of air bubbles in the lubricating grease and affecting the normal contact with the rubber roller.

[0021] The beneficial effects of this utility model are: This utility model allows all existing tooling models (applicable to CD6140A CNC lathes) to be installed on newly added GLS-200 CNC lathes in the workshop without any modifications, reducing costs and improving conversion flexibility.

[0027] Figure 1-6The connecting conversion device shown is suitable for machining lathe spindles of different specifications. It includes: a first machine tool spindle connecting plate 1 and a second machine tool spindle connecting plate 4, which are connected by a locating stop and secured with six M12X45 socket head cap screws 5; an intermediate connecting plate 2, positioned between the first machine tool spindle connecting plate 1 and the second machine tool spindle connecting plate 4; and a packing bolt 3, placed inside a hole in the second machine tool spindle connecting plate 4. Due to inertia, the packing bolt 3 remains within the oblong hole of the intermediate connecting plate 2, achieving a secure connection. In use, the GLS-200 first machine tool spindle connecting plate 1 and the CD6140A second machine tool spindle connecting plate 4 are connected by a locating stop and secured with six M12X45 socket head cap screws 5. The intermediate connecting plate 2 is pre-placed between the first machine tool spindle connecting plate 1 and the second machine tool spindle connecting plate 4, ensuring its orientation is as follows: Figure 2 As shown, the connection conversion device assembly, after being tightened with the M12X45 socket head cap screw 5, can be connected to the spindle of the GLS-200 CNC lathe through the stop. Then, by rotating the intermediate connecting disc 2 and tightening it with the packing bolt 3 and nut, all old-style water pump bodies and water pipes can be machined. The tooling suitable for the CD6140A CNC lathe can be connected to the GLS-200 CNC lathe through this connection conversion device, so that all models of old tooling can be installed on the newly added GLS-200 CNC lathe in the workshop without any modification.

[0028] Figure 2-6The system also includes: a lubrication device 6, which is mounted on the second machine tool spindle connecting plate 4. The lubrication device 6 includes: a slot 61, which is located on the second machine tool spindle connecting plate 4 and corresponds to the position of the oblong hole on the intermediate connecting plate 2; an oil reservoir 62, which is inserted into the slot 61 and fixed inside the slot 61 by screws 63, and is filled with lubricating grease; a concave frame 64, which is fixed to the side of the oil reservoir 62 near the intermediate connecting plate 2, and has a rectangular hole between the concave frame 64 and the oil reservoir 62; and a rubber roller 65, which is rotatably mounted on the concave frame 64 via bearings, and has its surface in contact with the surface of the intermediate connecting plate 2. A portion of the rubber roller 65 is located inside the rectangular hole and the oil reservoir 62 and is in contact with the lubricating grease. By setting up the lubrication device 6, the oil reservoir is first manually emptied... The oil reservoir 62 is inserted into the slot 61 and fixed by the screw 63, so that the oil reservoir 62 is fixedly mounted on the second machine tool spindle connecting plate 4, and the surface of the rubber roller 65 is in contact with the surface of the intermediate connecting disc 2. When the intermediate connecting disc 2 rotates, it causes the rubber roller 65 to rotate inside the concave frame 64 and the oil reservoir 62, so that the rubber roller 65 comes into contact with the lubricating grease inside the oil reservoir 62 during rotation, so that the lubricating grease adheres to the surface of the rubber roller 65 and is then applied to the intermediate connecting disc 2 during subsequent rotation, thereby completing the auxiliary lubrication of the intermediate connecting disc 2. This reduces the situation where the intermediate connecting disc 2 lacks lubricating oil, which would increase the friction between the intermediate connecting disc 2 and the second machine tool spindle connecting plate 4 and the packing bolt 3, affecting the service life of the intermediate connecting disc 2. At the same time, the intermediate connecting disc 2 can be automatically lubricated by the operator while rotating it, improving the convenience of lubrication.

[0029] Figure 2-6 Two guide plates 66 are symmetrically fixed to the inner wall of the oil reservoir 62 near the rubber roller 65. The guide plates 66 are triangular in shape. By setting the guide plates 66, the lubricating grease inside the oil reservoir 62 can be guided by the slope of the surface of the guide plates 66 to flow towards the center of the oil reservoir 62, reducing the possibility of some lubricating grease remaining inside the oil reservoir 62. An auxiliary plate 613 is fixed to one side of the oil reservoir 62. The auxiliary plate 613 is rectangular in shape. By setting the auxiliary plate 613, a point of force can be provided when the personnel manually pull out the oil reservoir 62, reducing the possibility of slipping when manually pulling the oil reservoir 62.

[0030] Figure 2-6A filling tube 69 is fixedly connected to one side of the oil reservoir 62 shown. The filling tube 69 is placed inside the oil reservoir 62 but not in contact with the inner wall of the oil reservoir 62. The end of the filling tube 69 on the outside of the oil reservoir 62 is threadedly connected to a sealing cap 610. By setting the filling tube 69, personnel can directly inject lubricating grease into the oil reservoir 62 through the filling tube 69, which is convenient for personnel to replenish the oil inside the oil reservoir 62. A rubber stopper 612 is fixedly connected to the inner wall of the sealing cap 610. The size and shape of the rubber stopper 612 are adapted to the size and shape of the inner wall of the filling tube. The rubber stopper 612 is placed inside the filling tube 69 and completely seals it. By setting the rubber stopper 612, the rubber stopper 612 can be inserted into the filling tube and completely seal it, preventing the lubricating grease inside the oil reservoir 62 from entering the filling tube and causing blockage, which would affect the subsequent normal oil filling.

[0031] Figure 2-6 Multiple anti-slip strips 611 are fixedly attached to the surface of the sealing cover 610 shown. The multiple anti-slip strips 611 are arranged at equal intervals. By setting the anti-slip strips 611, the friction between the hand and the surface of the sealing cover 610 can be increased, reducing the possibility of slippage when manually rotating the sealing cover 610. A spring rod 68 is slidably connected to the inner wall of the hole of the oil reservoir 62. The other end of the spring in the spring rod 68 is fixedly connected to the oil reservoir 62. A piston plate 67 is fixedly attached to the end of the spring rod 68 inside the oil reservoir 62. By setting the piston plate 67, under the reaction force of the spring in the spring rod 68, the spring rod 68 is always in the state of pushing the piston plate 67. After the piston plate 67 is pushed, it pushes the lubricating grease inside the oil reservoir 62 towards the rubber roller 65, reducing the possibility of the lubricating grease bulging and affecting the normal contact with the rubber roller 65.

[0032] Working principle: In use, this connection conversion device connects the GLS-200 first machine tool spindle connecting plate 1 and the CD6140A second machine tool spindle connecting plate 4 via a positioning stop, secured by six M12X45 socket head cap screws 5. The intermediate connecting disc 2 is pre-placed between the first machine tool spindle connecting plate 1 and the second machine tool spindle connecting plate 4. Note that its placement direction must be as follows... Figure 2 As shown, the connection conversion device assembly, after being tightened with the M12X45 socket head cap screw 5, can be connected to the spindle of the GLS-200 CNC lathe through the stop. Then, by rotating the intermediate connecting disc 2 and tightening it with the packing bolt 3 and nut, all old-style water pump bodies and water pipes can be machined. The tooling suitable for the CD6140A CNC lathe can be connected to the GLS-200 CNC lathe through this connection conversion device, so that all models of old tooling can be installed on the newly added GLS-200 CNC lathe in the workshop without any modification.

[0033] First, manually insert the oil reservoir 62 into the slot 61 and fix it with screws 63, so that the oil reservoir 62 is fixedly mounted on the second machine tool spindle connecting plate 4, making the surface of the rubber roller 65 fit against the surface of the intermediate connecting disc 2. Then, inject lubricating grease into the oil reservoir 62 through the oil injection pipe. When the intermediate connecting disc 2 rotates, it causes the rubber roller 65 to rotate inside the concave frame 64 and the oil reservoir 62, so that the rubber roller 65 comes into contact with the lubricating grease inside the oil reservoir 62 during rotation, so that the lubricating grease adheres to the surface of the rubber roller 65, and is then spread onto the intermediate connecting disc 2 during the subsequent rotation of the rubber roller 65, thereby completing the auxiliary lubrication of the intermediate connecting disc 2.
