Description

Technical Field

[0001] The utility model relates to the field of hole machining, in particular to a hole machining device for a measuring instrument cylinder body. Background Art

[0002] Generally, CNC machining usually refers to computer numerical control precision machining, such as CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. The feed machining route of a CNC lathe refers to the path that the turning tool travels from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the machining program, including the path of cutting machining and the non-cutting idle stroke paths such as tool entry and exit. The feed route for finish machining basically follows the part contour sequence. Therefore, the key point in determining the feed route is to determine the feed route for rough machining and idle stroke. In CNC lathe machining, the determination of the machining route generally follows the following principles: it should ensure the accuracy and surface roughness of the machined workpiece, make the machining route the shortest, reduce the idle stroke time, improve the machining efficiency, simplify the workload of numerical calculation as much as possible, simplify the machining program, and for some repeatedly used programs, subroutines should be used.

[0003] In the prior art, during the process of drilling holes in the side wall of a cylinder body using a CNC machining center, when drilling holes are required on both sides of the side wall of the cylinder body, it is impossible to complete drilling on both sides of the cylinder body simultaneously, making it difficult to meet the requirements. Therefore, a hole machining device for a measuring instrument cylinder body is now proposed. Summary of the Utility Model

[0004] In order to improve the problem in the prior art that during the process of drilling holes in the side wall of a cylinder body using a CNC machining center, when drilling holes are required on both sides of the side wall of the cylinder body, it is impossible to complete drilling on both sides of the cylinder body simultaneously, making it difficult to meet the requirements, the utility model provides a hole machining device for a measuring instrument cylinder body.

[0005] The utility model provides a hole machining device for a measuring instrument cylinder body, adopting the following technical scheme:

[0006] A hole machining device for a measuring instrument cylinder body includes a machining base. Two symmetric first electric push rods are fixedly installed on the inner wall of the top of the machining base. The bottom ends of the two first electric push rods are fixedly connected to a sliding plate, and the sliding plate is slidably connected to the machining base. A machine box is fixedly installed on the sliding plate, and a double-shaft motor is fixedly installed inside the machine box. A driving box is fixedly installed at the bottom of the sliding plate. A partition is fixedly installed inside the driving box, and a driving motor is fixedly installed on the partition. An adjusting mechanism is arranged on the sliding plate, and a bilateral drilling mechanism is arranged below the sliding plate.

[0007] By adopting the above technical scheme, with the bilateral drilling mechanism, drilling can be performed on both sides of the cylinder body simultaneously, improving the work efficiency.

[0008] Optionally, second electric push rods are fixedly arranged on the inner walls on both sides of the processing seat, and arc-shaped clamping blocks are fixedly connected to one ends of the two second electric push rods.

[0009] By adopting the above technical solution, the two second electric push rods are used to drive the two arc-shaped clamping blocks to approach each other to fix the cylinder body.

[0010] Optionally, the adjusting mechanism includes two adjusting screws fixedly connected to the output shafts of the double-shaft motor. The two adjusting screws are both rotatably connected to the chassis. Threaded sleeves are threadedly connected to the two adjusting screws, and moving plates are fixedly connected to the two threaded sleeves.

[0011] By adopting the above technical solution, since the thread directions of the two adjusting screws are opposite to the thread directions of the two threaded sleeves respectively, the adjusting screws can drive the two threaded sleeves to approach or move away from each other.

[0012] Optionally, two sliding holes are symmetrically formed in the sliding plate. The two moving plates are respectively located in the two sliding holes. Two sliding grooves are arranged on the two side walls of the two sliding holes. Limiting plates are slidably connected in the four sliding grooves, and the four limiting plates are respectively fixedly connected to the two sides of the two moving plates.

[0013] By adopting the above technical solution, when the four limiting plates slide in the four sliding grooves, the horizontal movement of the two moving plates can be ensured.

[0014] Optionally, a driving rod is rotatably connected to the bottom of the partition plate. The driving rod is fixedly connected to the output shaft of the driving motor. A first bevel gear is fixedly connected to the bottom end of the driving rod. Transmission rods are rotatably connected to both sides of the driving box. Second bevel gears are fixedly connected to one ends of the two transmission rods. The two second bevel gears are both meshed with the first bevel gear.

[0015] By adopting the above technical solution, due to the meshing between the two second bevel gears and the first bevel gear, the first bevel gear drives the two transmission rods to rotate through the two second bevel gears.

[0016] Optionally, the bilateral drilling mechanism includes gear shafts respectively fixedly connected to the outer walls of the two transmission rods. One ends of the two moving plates are rotatably connected to first rotating rods. Gears are fixedly connected to one ends of the two first rotating rods. The two gears are respectively meshed with the two gear shafts.

[0017] By adopting the above technical solution, after the two gears can move horizontally, the meshing transmission with the two gear shafts can also be ensured.

[0018] Optionally, a second rotating rod is rotatably connected to one side of each of the two moving plates. Driving wheels are fixedly connected to the two first rotating rods and the two second rotating rods. Two drive belts are respectively connected between the four driving wheels in a driving manner. Drill bits are fixedly connected to one end of each of the two second rotating rods.

[0019] By adopting the above technical solution, when the two second rotating rods rotate, they can drive the two drill bits to rotate and drill the two sides of the cylinder body.

[0020] Optionally, a controller is fixedly provided on one side of the processing base, and a placement groove is provided on the processing base.

[0021] By adopting the above technical solution, the placement groove is convenient for placing the cylinder body.

[0022] In summary, the present utility model has the following beneficial effects:

[0023] 1. In the present utility model, the adjusting screw drives the two screw sleeves to approach each other, and the two screw sleeves drive the two moving plates to approach each other. At the same time, the four limiting plates can be used to limit the two moving plates, so as to ensure the horizontal movement of the two moving plates and make the two drill bits fit with the cylinder body, thereby achieving the adjustment effect.

[0024] 2. In the present utility model, the two transmission rods drive the two gears to rotate through the two gear shafts. The two gears drive the two first rotating rods fixedly connected thereto to rotate. Since there are two drive belts driving between the four driving wheels, the two second rotating rods can follow the two first rotating rods to rotate. The two second rotating rods drive the two drill bits to rotate and drill the two sides of the cylinder body, thereby achieving the effect of simultaneous bilateral drilling and improving the working efficiency.

The two second electric push rods 9 drive the two arc-shaped clamping blocks 10 to approach each other to limit and fix the cylinder body.

[0032] Referring to Figure 1 and Figure 2 , an adjusting mechanism is provided on the slide plate 3. The adjusting mechanism includes two adjusting screw rods 11 fixedly connected to the output shafts of the biaxial motor 5. The two adjusting screw rods 11 are both rotatably connected to the chassis 4. Screw sleeves 12 are threadedly connected to the two adjusting screw rods 11. Moving plates 13 are fixedly connected to the two screw sleeves 12. Two slide holes 14 are symmetrically formed on the slide plate 3. The two moving plates 13 are respectively located in the two slide holes 14. Two slide grooves 15 are provided on both side walls of the two slide holes 14. Limit plates 16 are slidably connected in the four slide grooves 15. The four limit plates 16 are respectively fixedly connected to both sides of the two moving plates 13. The four limit plates 16 can be used to limit the two moving plates 13, so as to ensure the horizontal movement of the two moving plates 13.

[0033] Referring to Figure 2 and Figure 3, a driving rod 17 is rotatably connected to the bottom of the partition plate 7. The driving rod 17 is fixedly connected to the output shaft of the driving motor 8. A first bevel gear 18 is fixedly connected to the bottom end of the driving rod 17. Transmission rods 19 are rotatably connected to both sides of the driving box 6. Second bevel gears 20 are fixedly connected to one ends of the two transmission rods 19. The two second bevel gears 20 are both meshed with the first bevel gear 18. Due to the meshing of the two second bevel gears 20 with the first bevel gear 18, the first bevel gear 18 can drive the two second bevel gears 20 to rotate.

[0034] Referring to Figure 2 and Figure 3 , a double-sided drilling mechanism is provided below the sliding plate 3. The double-sided drilling mechanism includes gear shafts 21 fixedly connected to the outer walls of the two transmission rods 19 respectively. One ends of the two moving plates 13 are rotatably connected to first rotating rods 22. Gears 23 are fixedly connected to one ends of the two first rotating rods 22. The two gears 23 are respectively meshed with the two gear shafts 21. One ends of the two moving plates 13 are rotatably connected to second rotating rods 24. Transmission wheels 25 are fixedly connected to the two first rotating rods 22 and the two second rotating rods 24. Two transmission belts 26 are respectively connected between the four transmission wheels 25 in a transmission manner. Drill bits 27 are fixedly connected to one ends of the two second rotating rods 24. The two second rotating rods 24 drive the two drill bits 27 to rotate and drill both sides of the cylinder body, thereby achieving the effect of double-sided simultaneous drilling, improving the working efficiency.

[0035] The implementation principle of the present utility model is as follows: When using a processing device for the holes of a measuring instrument cylinder body, place the cylinder body in the placement groove 29. Use the controller 28 to control the two second electric push rods 9 to drive the two arc-shaped clamping blocks 10 to move closer to each other to limit and fix the cylinder body. The controller 28 controls the two first electric push rods 2 to drive the slide plate 3 to move downward, and makes the two drill bits 27 move downward to adjust to the position where drilling is required. Then, start the double-shaft motor 5 through the controller 28. The output shafts of the double-shaft motor 5 drive the two adjusting screws 11 to rotate. Due to the threaded connection between the two screw sleeves 12 and the two adjusting screws 11, the adjusting screws 11 drive the two screw sleeves 12 to move closer to each other. The two screw sleeves 12 drive the two moving plates 13 to move closer to each other. At the same time, the two moving plates 13 can be limited by the four limiting plates 16, so as to ensure the horizontal movement of the two moving plates 13 and make the two drill bits 27 fit with the cylinder body. Start the driving motor 8 through the controller 28, so that the output shaft of the driving motor 8 drives the driving rod 17 to rotate. The driving rod 17 drives the fixedly connected first bevel gear 18 to rotate. Due to the meshing of the two second bevel gears 20 with the first bevel gear 18, the first bevel gear 18 can drive the two second bevel gears 20 to rotate. The two second bevel gears 20 drive the two fixedly connected transmission rods 19 to rotate. Due to the meshing between the two gears 23 and the two gear shafts 21, the two transmission rods 19 can drive the two gears 23 to rotate through the two gear shafts 21. The two gears 23 drive the two fixedly connected first rotating rods 22 to rotate. Since there are two transmission belts 26 driving among the four transmission wheels 25, the two second rotating rods 24 can follow the two first rotating rods 22 to rotate. The two second rotating rods 24 drive the two drill bits 27 to rotate, and drill the two sides of the cylinder body, thus achieving the effect of simultaneous bilateral drilling and improving the work efficiency.
