Description

Technical Field

[0001] This utility model relates to the technical field of grinding and polishing devices, and in particular to a grinding and polishing device for chamfering locomotive parts. Background Technology

[0002] Chinese patent document CN217096616U discloses a chamfering device for mechanical parts. This utility model discloses a chamfering device for mechanical parts, relating to the field of parts processing technology. It includes: a processing frame, two chamfering devices symmetrically fixed on both sides of the outer wall of the chamfering devices, and a rotating mechanism located inside the processing frame. The rotating mechanism includes a placement table, a rotating plate, and a driving component. This chamfering device drives the rotating plate to rotate through the driving component inside the processing frame, causing the placement table to rotate at a fixed angle. This allows the two chamfering devices to simultaneously chamfer multiple sides of the mechanical part, improving chamfering efficiency and avoiding the low efficiency of chamfering only one side. Furthermore, the device uses two sets of fixing mechanisms to fix the mechanical part, preventing the chamfering devices from contacting the mechanical part during chamfering, which could easily cause the mechanical part to shift and result in substandard chamfered dimensions.

[0003] However, the above technical solution has some drawbacks in use. Because it only fixes the two sides of the rod-shaped mechanical part during fixing, the mechanical part will shift during chamfering and grinding, resulting in poor fixing effect and low chamfering efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where only the two sides of the rod-shaped mechanical parts are fixed during the fixing process, and the mechanical parts will shift during chamfering and grinding, resulting in poor fixing effect and low chamfering efficiency. Therefore, a chamfering and grinding device for locomotive parts is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A chamfering and grinding device for locomotive components includes four base columns, a table, and chamfering components. The table is fixedly connected to the upper ends of the four base columns, and the chamfering components are fixedly connected to the upper ends of the table. The grinding device also includes two propulsion mechanisms, which are symmetrically located on the table. The propulsion mechanisms can use propulsion force to fix the components.

[0006] Preferably, the propulsion mechanism includes: a stepped sliding hole, a gear, a drive rod, a first slider, an L-shaped rod, a sliding hole, a second slider, a Z-shaped rod, a hollow sleeve, a support column, an L-shaped connecting rod, a sliding block, a V-shaped rod, two limit columns, and a power assembly; A stepped sliding hole is made on the tabletop. A gear is rotatably connected to the bottom end of the tabletop. One end of the driving rod is fixedly connected to the gear. A sliding hole is made on the long end of the L-shaped connecting rod. The first slider is rotatably connected to the other end of the driving rod and slides in the sliding hole. One end of the Z-shaped rod and the support column is rotatably connected to the bottom end of the tabletop. The corner of the L-shaped rod and one end of the hollow sleeve plate are respectively rotatably fitted onto the cylindrical end of the Z-shaped rod and the other end of the support column. The second slider is rotatably connected to the other end of the L-shaped rod and slides in the hollow sleeve plate. The two ends of the L-shaped connecting rod are rotatably connected to the other end of the hollow sleeve plate and the bottom end of the sliding block, respectively. The protruding end of the corner of the V-shaped rod is fixedly connected to the upper end of the sliding block. Both the protruding end of the corner of the V-shaped rod and the sliding block slide in the stepped sliding hole. Two limiting posts are vertically fixedly connected to the two ends of the V-shaped rod.

[0007] Furthermore, the rotation of the gear causes the drive rod and the first slider to rotate along with the gear. Simultaneously, the first slider slides along the sliding hole on the L-shaped rod, causing the corner of the L-shaped rod to rotate around the cylindrical end of the Z-shaped rod. At the same time, the second slider on the L-shaped rod slides inside the hollow sleeve, causing the hollow sleeve to swing around the support column. This swinging force of the hollow sleeve can be used to advance the L-shaped connecting rod and the sliding block, and then the pushing force of the sliding block can be used to advance the V-shaped rod and the two limiting columns. At the same time, the two ends of the L-shaped connecting rod rotate around the other end of the hollow sleeve and the sliding block, respectively. The protruding end at the corner of the V-shaped rod and the sliding block slide and advance within the stepped sliding hole. This allows the V-shaped rod and the limiting columns to be fixed to the locomotive parts by the mutual pushing force of the two pushing mechanisms.

[0008] Preferably, the power assembly includes: a fixed block, a hydraulic rod, and a U-shaped rack; The fixing block is fixedly connected to the bottom of the tabletop. The two ends of the hydraulic rod are fixedly connected to the fixing block and one side of the U-shaped rack, respectively. The teeth on the inner walls of the two sides of the U-shaped rack mesh with two gears.

[0009] Furthermore, by starting with a hydraulic rod, the hydraulic rod extends to advance the U-shaped rack, thereby using the meshing force between the U-shaped rack and the gear to make the gear rotate, thus providing power for the rotation of the gear.

[0010] Preferably, a rubber sleeve is fixedly fitted on the limiting post.

[0011] Furthermore, when fixing locomotive parts using the limiting post, the rubber sleeve contacts the locomotive parts, thus preventing damage to the locomotive parts during fixing.

[0012] Preferably, the bottom end of the tabletop has two sliding grooves, and the two protruding ends of the U-shaped rack slide in the two sliding grooves respectively.

[0013] Furthermore, by pushing the U-shaped rack forward, the protruding end of the U-shaped rack slides within the groove, thereby limiting the movement of the U-shaped rack.

[0014] Preferably, a dust cover is fixedly fitted on the outer side of the propulsion mechanism, the dust cover is bolted to the bottom end of the table, and the bottom column is fixedly inserted through the dust cover.

[0015] Furthermore, by covering the outside of the propulsion mechanism with a dust cover, a large amount of dust can be prevented from affecting the propulsion mechanism.

[0016] Beneficial effects: 1. The gear rotates, causing the drive rod and the first slider to rotate with it. Simultaneously, the first slider slides along the sliding hole on the L-shaped rod, causing the corner of the L-shaped rod to rotate around the cylindrical end of the Z-shaped rod. At the same time, the second slider on the L-shaped rod slides inside the hollow sleeve, causing the hollow sleeve to swing around the support column. This swinging force of the hollow sleeve can be used to advance the L-shaped connecting rod and the sliding block, and then the pushing force of the sliding block can be used to advance the V-shaped rod and the two limiting columns. At the same time, the two ends of the L-shaped connecting rod rotate around the other end of the hollow sleeve and the sliding block, respectively. The protruding end at the corner of the V-shaped rod and the sliding block slide and advance within the stepped sliding hole. This allows the V-shaped rod and the limiting columns to be fixed to the locomotive parts by the mutual pushing force of the two pushing mechanisms.

[0017] 2. The system is activated by a hydraulic rod, which extends to advance the U-shaped rack. The meshing force between the U-shaped rack and the gear causes the gear to rotate, thus providing power for the gear's rotation.

[0018] In this invention, the cooperation between the propulsion mechanism and the power component can prevent the mechanical parts from shifting during chamfering and grinding, thereby effectively improving the fixing effect and the efficiency of chamfering. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A chamfering and grinding device for locomotive parts includes four base columns 1, a table 2, and a chamfering component 3. The table 2 is fixedly connected to the upper end of the four base columns 1, and the chamfering component 3 is fixedly connected to the upper end of the table 2. The grinding device also includes two propulsion mechanisms, which are symmetrically located on the table 2. The propulsion mechanisms can use propulsion force to fix the components.

[0023] In this utility model, the propulsion mechanism includes: a stepped sliding hole 9, a gear 10, an active rod 11, a first slider 12, an L-shaped rod 13, a sliding hole 14, a second slider 15, a Z-shaped rod 16, a hollow sleeve plate 17, a support column 18, an L-shaped connecting rod 19, a sliding block 20, a V-shaped rod 21, two limiting columns 22, and a power assembly. like Figure 1 and Figure 3As shown, a stepped sliding hole 9 is formed on the tabletop 2, a gear 10 is rotatably connected to the bottom end of the tabletop 2, one end of the driving rod 11 is fixedly connected to the gear 10, a sliding hole 14 is formed on the long end of the L-shaped connecting rod 19, a first slider 12 is rotatably connected to the other end of the driving rod 11 and slides in the sliding hole 14, one end of the Z-shaped rod 16 and the support column 18 are rotatably connected to the bottom end of the tabletop 2, and the corner of the L-shaped rod 13 and one end of the hollow sleeve plate 17 are respectively rotatably sleeved on the Z-shaped rod 16. On the cylindrical end and the other end of the support column 18, the second slider 15 is rotatably connected to the other end of the L-shaped rod 13 and slides within the hollow sleeve plate 17. The two ends of the L-shaped connecting rod 19 are rotatably connected to the other end of the hollow sleeve plate 17 and the bottom end of the sliding block 20, respectively. The protruding end of the V-shaped rod 21 at the corner is fixedly connected to the upper end of the sliding block 20, and both the protruding end of the V-shaped rod 21 at the corner and the sliding block 20 slide within the stepped sliding hole 9. The two limiting posts 22 are vertically fixedly connected to the V-shaped rod 21 at the other end of the support column 18. The two ends of the L-shaped rod 21 are rotated by the gear 10, which in turn causes the driving rod 11 and the first slider 12 to rotate with the rotation of the gear 10. At the same time, the first slider 12 slides along the sliding hole 14 on the L-shaped rod 13, so that the corner of the L-shaped rod 13 rotates around the cylindrical end of the Z-shaped rod 16. Meanwhile, the second slider 15 on the L-shaped rod 13 slides inside the hollow sleeve plate 17, so that the hollow sleeve plate 17 swings around the support column 18. In this way, the swing of the hollow sleeve plate 17 can be used to... The power pushes the L-shaped connecting rod 19 and the sliding block 20, and then uses the pushing force of the sliding block 20 to push the V-shaped rod 21 and the two limiting posts 22. At the same time, the two ends of the L-shaped connecting rod 19 rotate with the other end of the hollow sleeve plate 17 and the sliding block 20 as the center, respectively. The protruding end of the V-shaped rod 21 at the corner and the sliding block 20 slide and push in the stepped sliding hole 9. In this way, the V-shaped rod 21 and the limiting posts 22 can be fixed to the locomotive parts by using the mutual pushing force of the two pushing mechanisms.

[0024] In this utility model, the power assembly includes: a fixed block 5, a hydraulic rod 6, and a U-shaped rack 7; like Figure 2 and Figure 4 As shown, the fixing block 5 is fixedly connected to the bottom end of the tabletop 2. The two ends of the hydraulic rod 6 are fixedly connected to the fixing block 5 and one side of the U-shaped rack 7, respectively. The teeth on the inner walls of both sides of the U-shaped rack 7 mesh with the two gears 10. When the hydraulic rod 6 is activated, the hydraulic rod 6 extends to push the U-shaped rack 7, thereby using the meshing force between the U-shaped rack 7 and the gears 10 to make the gears 10 rotate, thus providing power for the rotation of the gears 10.

[0025] like Figure 1 and Figure 3 As shown, a rubber sleeve 23 is fixedly sleeved on the limiting post 22. When the locomotive parts are fixed by the limiting post 22, the rubber sleeve 23 is in contact with the locomotive parts, which can avoid damage to the locomotive parts during the fixing process.

[0026] like Figure 2 As shown, the bottom end of the table board 2 has two sliding grooves 8. The two protruding ends of the U-shaped rack 7 slide in the two sliding grooves 8 respectively. When the U-shaped rack 7 is pushed forward, the protruding ends of the U-shaped rack 7 slide in the sliding grooves 8, thereby limiting the position of the U-shaped rack 7.

[0027] like Figure 1 As shown, a dust cover 4 is fixedly fitted on the outside of the propulsion mechanism. The dust cover 4 is bolted to the bottom of the table 2, and the bottom column 1 is fixedly inserted through the dust cover 4. By fitting the dust cover 4 on the outside of the propulsion mechanism, a large amount of dust can be avoided from affecting the propulsion mechanism.

[0028] It should be noted that the specific type of chamfering component 3 and hydraulic rod 6 used can be selected by those skilled in the art. Furthermore, the chamfering component 3 and hydraulic rod 6 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0029] The working principle of this utility model: First, place the locomotive component on the table 2, making it contact the chamfered portion of the chamfered component 3. Simultaneously, the spring within the chamfered portion is compressed. Then, activate the hydraulic rod 6, which extends to advance the U-shaped rack 7. At the same time, the protruding end of the U-shaped rack 7 slides within the slide groove 8. This utilizes the meshing force between the U-shaped rack 7 and the gear 10 to rotate the gear 10. Consequently, the drive rod 11 and the first slider 12 rotate along with the gear 10. Simultaneously, the first slider 12 slides along the sliding hole 14 on the L-shaped rod 13, causing the corner of the L-shaped rod 13 to rotate around the cylindrical end of the Z-shaped rod 16. Simultaneously, the second slider 15 on the L-shaped rod 13 slides within the hollow sleeve plate 17, causing the hollow sleeve plate 17 to rotate around the support column 18. The hollow sleeve 17 swings in a circular motion, which allows the L-shaped connecting rod 19 and the sliding block 20 to be pushed forward by the swinging force of the hollow sleeve 17. In turn, the sliding block 20 pushes forward the V-shaped rod 21 and the two limiting posts 22. At the same time, the two ends of the L-shaped connecting rod 19 rotate with the other end of the hollow sleeve 17 and the sliding block 20 as the center, respectively. The protruding end of the V-shaped rod 21 at the corner and the sliding block 20 slide and push forward in the stepped sliding hole 9. In this way, the rubber sleeve 23 on the V-shaped rod 21 and the limiting post 22 can be fixed to the locomotive parts by the mutual pushing force of the two pushing mechanisms. Then, the chamfering component 3 is activated. The spring in the chamfering component 3 pushes forward to extend the chamfered part, and the extended part cannot be detached. In this way, the fixed locomotive parts can be chamfered.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
