Description

Technical Field

[0001] The utility model belongs to the technical field of telescopic cylinder grinding, in particular to a telescopic cylinder grinding device. Background Art

[0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The air in the engine cylinder converts heat energy into mechanical energy through expansion; the gas in the compressor cylinder is compressed by the piston to increase the pressure.

[0003] For example, the patent number CN219075224U discloses a grinding device for cylinder mold production, including a bottom plate, a support seat fixedly connected to the top of the bottom plate, a driving motor fixedly installed on the inner wall of the supporting seat, a mold seat fixedly connected to the output shaft of the driving motor, and a uniformly distributed extension groove on the mold seat. The utility model supports cylinder molds of different specifications by adjusting the extension plate, changes the position of the pressure plate by an electric push rod, limits the cylinder mold to avoid displacement during the grinding process, and grinds both sides of cylinder modules of different specifications at the same time by changing the distance between the two grinding rollers, and rotates the storage seat by the driving motor, so that the cylinder mold can be evenly polished around the cylinder mold without repeated clamping, which solves the problem that the previous grinding device for cylinder mold production cannot quickly grind molds of different specifications.

[0004] In the current existing technology, cylinders of different specifications are polished by adjusting the extension plate, but the polishing equipment only polishes the outside of the cylinder. The inside polishing also requires the cylinder to be removed from the fixed table and then polished with a manual handheld polishing wheel, which is very troublesome and inefficient.

[0005] Therefore, a telescopic cylinder grinding device is proposed to address the above problems. Utility Model Content

The support plate 7 is provided with an inner grinding wheel 8, and the first rotating column 29 is driven to rotate by the third rotating motor 28. The rotation of the first rotating column 29 drives the inner grinding wheel 8 to rotate, and the inner grinding wheel 8 rotates to grind the inner wall of the unjoined telescopic cylinder tube, and then the second rotating motor 26 drives the first rotating column 29 to rotate. The rotating shaft 27 rotates, and the rotating shaft 27 drives the turntable 4 to rotate, so that the unspliced ​​telescopic cylinder tube rotates, and then the grinding device is used to grind the outer wall of the unspliced ​​telescopic cylinder tube. In this way, the outer wall and the inner wall of the unspliced ​​telescopic cylinder tube can be grinded at the same time, avoiding only grinding the outer wall of the unspliced ​​telescopic cylinder tube. After the outer wall grinding is completed, the unspliced ​​telescopic cylinder tube is removed and the inner wall is grinded by a manual hand-held grinding wheel, which makes the operation inconvenient and wastes a lot of time.

[0026] Further, such as Figure 2 and Figure 4As shown, a first thread groove 11 is provided on the turntable 4; a bidirectional screw rod 12 is rotatably connected in the first thread groove 11; an internal fixing clip 10 is threadedly connected to the bidirectional screw rod 12; two internal fixing clips 10 are provided and symmetrically arranged on the bidirectional screw rod 12; an external fixing clip 5 is fixedly connected to the turntable 4; two external fixing clips 5 are provided and symmetrically arranged at both ends of the first thread groove 11; a first screw motor 9 is fixedly connected to the side wall of the turntable 4.

When the bidirectional screw rod 12 rotates, the internal fixing clip 10 moves inward or outward at the same time, and cooperates with the external fixing clip 5 fixed on the turntable 4 to fix the unjoined telescopic cylinder tube placed on the turntable 4 to avoid loosening and sliding during grinding.

[0027] Further, such as Figure 1 and Figure 2 As shown, the top of the workbench 1 is provided with a second thread groove 13; a one-way screw 14 is rotatably connected in the second thread groove 13; a second screw motor 21 is fixedly connected to the side wall of the workbench 1 and the horizontal position of the one-way screw 14; a thread block 20 is threadedly connected to the one-way screw 14; a moving plate 17 is fixedly connected to the top of the thread block 20; a second rotating column 30 is rotatably connected to the moving plate 17; a side grinding wheel 18 is fixedly connected to the end of the second rotating column 30 away from the moving plate 17; a first rotating wheel 18 is fixedly connected to the end of the moving plate 17 away from the second rotating column 30 The driving motor 16, when working, drives the one-way screw 14 to rotate in the second thread groove 13 through the second screw motor 21, and the one-way screw 14 rotates to drive the threaded block 20 connected by the thread to move, and the moving plate 17 fixedly connected to the top of the threaded block 20 also moves along, and the moving plate 17 moves to a certain position away from the unspliced ​​telescopic cylinder tube and then stops moving, and then the first rotating motor 16 is started to drive the second rotating column 30 to rotate, and the rotation of the second rotating column 30 drives the side grinding wheel 18 to rotate, and the side grinding wheel 18 grinds the bottom of the unspliced ​​telescopic cylinder tube.

[0028] Further, such as Figure 4As shown, a support block 25 is fixedly connected to one side of the workbench 1; a support rod 22 is fixedly connected to the top of the support block 25; two support rods 22 are provided and symmetrically arranged on the top of the support block 25; one end of the support rod 22 away from the support block 25 is fixedly connected to a second telescopic rod 23; the output end of the second telescopic rod 23 is fixedly connected to a grinding plate 24. During operation, when the turntable 4 rotates to drive the unspliced ​​telescopic cylinder tube to rotate, the second telescopic rod 23 on the support rod 22 is extended and retracted, and the grinding plate 24 at the output end is pushed toward the unspliced ​​telescopic cylinder tube, and the grinding plate 24 can grind the side wall of the unspliced ​​telescopic cylinder tube and then stop extending and retracting. Because the rotation of the turntable 4 causes the unspliced ​​telescopic cylinder tube to rotate all the time, the grinding plate 24 grinds the outer side wall of the unspliced ​​telescopic cylinder tube.

[0030] Further, such as Figure 1 As shown, a support leg 2 is fixedly connected to the bottom of the workbench 1; there are four support legs 2, which are respectively arranged at the four corners of the bottom of the workbench 1.

[0031] Working principle: The unjoined telescopic cylinder tube is fixed by placing it on the fixing clamp in the fixing assembly. After the unjoined telescopic cylinder tube is fixed, the first telescopic rod 6 is driven to extend and retract by an external driving motor, and the support plate 7 at the output end of the first telescopic rod 6 is moved. The support plate 7 is provided with an inner grinding wheel 8. The first rotating column 29 is driven to rotate by the third rotating motor 28. The rotation of the first rotating column 29 drives the inner grinding wheel 8 to rotate. The inner grinding wheel 8 rotates to grind the inner wall of the unjoined telescopic cylinder tube. Then, the second rotating motor 26 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the turntable 4 to rotate, so that the unspliced ​​telescopic cylinder tube rotates, and then the grinding device is used to grind the outer wall of the unspliced ​​telescopic cylinder tube. In this way, the outer wall and the inner wall of the unspliced ​​telescopic cylinder tube can be grinded at the same time, avoiding the problem of only grinding the outer wall of the unspliced ​​telescopic cylinder tube. After the outer wall grinding is completed, the unspliced ​​telescopic cylinder tube is removed and the inner wall is grinded by a manual hand-held grinding wheel, which makes the operation inconvenient and wastes a lot of time.
