Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a drilling equipment for the production of drive shafts. Background Technology

[0002] Drilling equipment for drive shaft production is used to drill holes in drive shafts. Drive shafts are common components in the automotive, machinery, and other fields, requiring drilling at specific locations and angles to install other components or connect to transmission devices.

[0003] Patent document CN212310881U discloses a drilling device for producing drive shafts. The protected claim includes a fixed base plate, a processing worktable fixedly connected to the top of the fixed base plate, support legs fixedly connected to both the front and rear ends of the top of the processing worktable, a limit ring fixedly connected to the top of the support legs, and a drive shaft component placed inside the limit ring. This drilling device for producing drive shafts, through the setting of a limit ring, guide rod, cylinder, drilling machine, vertical fixed side panel one, vertical fixed side panel two, pressure plate, rubber plate, through groove, spring, and a limit groove on the top of the drive shaft, solves the problem that drilling drive shafts is generally done individually, preventing batch drilling and thus reducing drilling efficiency. This allows for batch drilling of drive shafts, improving work efficiency, and simultaneously provides effective limit fixing of the drive shaft, enhancing its stability during drilling.

[0004] The drilling device for drive shaft production in the aforementioned published documents mainly considers the drilling of multiple drive shafts and the use of pressure plates, springs and rubber plates to fix the drive shafts. However, it does not take into account the poor stability when using pressure plates, springs and rubber plates to fix the drive shafts. During the drilling of drive shafts, the drive shafts are prone to slight vibrations, which affects the stability during drilling. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for the production of drive shafts, which aims to solve the problem of poor clamping stability of drive shafts in existing drilling devices for drive shaft production.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a drilling device for producing drive shafts, comprising a base, guide posts at the four corners of the top of the base, a top plate at the top of the guide posts, a pressure plate passing through the guide posts between the top plate and the base, a cylinder at the bottom center of the top plate, and the telescopic end of the cylinder being fixedly connected to the pressure plate, multiple sets of drilling machines at the bottom of the pressure plate, multiple sets of through slots symmetrically provided through the top of the base, and symmetrically provided on the top of the base for drilling through the drive shaft. The arc-shaped support base for initial positioning of the moving shaft body has an internal cavity. A rotating shaft is rotatably mounted inside the cavity. The outer surface of the rotating shaft has multiple sets of threaded segments, which are symmetrically arranged positive and negative threads. Threaded sliders are threadedly connected to both the positive and negative threads. A C-shaped frame is mounted on the top of the threaded slider and passes through the inside of a through groove. An arc-shaped clamping block is mounted at the end of the C-shaped frame above the through groove. A drive mechanism for driving the rotating shaft to rotate is mounted on the outside of the base.

[0007] Preferably, the driving mechanism is a motor disposed outside the base, with the output end of the motor passing through the interior of the base and connected to the end of the rotating shaft to drive the rotating shaft to rotate inside the cavity.

[0008] Preferably, the base is provided with support legs at all four corners of its bottom.

[0009] Preferably, a drawer is provided on one side of the base, and the drawer is located inside the cavity.

[0010] Preferably, the inner side of the arc-shaped clamping block is provided with an anti-slip pad.

[0011] Preferably, at least three drilling machines are provided.

[0012] The beneficial effects of this utility model are:

[0013] In use, this invention places the drive shaft body on an arc-shaped support, thus initially positioning the drive shaft body. Then, a drive mechanism rotates the shaft. As the shaft rotates, the threaded sliders on the threaded section move towards each other. The limiting effect between the grommets and the through slot prevents the threaded sliders from rotating with the shaft. The movement of the threaded sliders towards each other causes the grommets to move towards each other, which in turn causes two sets of arc-shaped clamping blocks to clamp and fix both sides of the drive shaft body. This ensures the drive shaft body is well-clamped and fixed before drilling, improving the clamping stability of the drilling device used in drive shaft production and enabling stable drilling operations.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, a drilling device for producing a drive shaft includes a base 1. Guide posts 2 are provided at each of the four corners of the top of the base 1. A top plate 3 is provided on the top of each guide post 2. A pressure plate 4 passes through the guide posts 2 between the top plate 3 and the base 1. A cylinder 5 is located at the center of the bottom of the top plate 3, and the telescopic end of the cylinder 5 is fixedly connected to the pressure plate 4. Multiple drilling machines 6 are provided at the bottom of the pressure plate 4. Multiple through slots 11 are symmetrically provided through the top of the base 1. Arc-shaped bearings for initial positioning of the drive shaft body 13 are symmetrically provided on the top of the base 1. The base 1 has a cavity 7 inside, and a rotating shaft 8 is rotatably mounted inside the cavity 7. The outer surface of the rotating shaft 8 is provided with multiple sets of threaded sections 16, which are symmetrically arranged positive and negative threads. Threaded sliders 9 are threadedly connected to both the positive and negative threads. A shaped bracket 10 is provided on the top of the threaded slider 9, and the shaped bracket 10 passes through the inside of the through groove 11. An arc-shaped clamping block 12 is provided at the end of the shaped bracket 10 above the through groove 11. A drive mechanism 14 for driving the rotating shaft 8 to rotate is provided on the outside of the base 1.

[0021] In this embodiment, the drive shaft body 13 is initially positioned by placing it on the arc-shaped support 18. Then, the drive mechanism 14 rotates the shaft 8. When the shaft 8 rotates, the threaded sliders 9 on the threaded section 16 move towards each other. The limiting effect between the mortise bracket 10 and the through groove 11 prevents the threaded sliders 9 from rotating with the shaft 8. The movement of the threaded sliders 9 towards each other causes the mortise bracket 10 to move towards each other. The movement of the mortise bracket 10 towards each other causes the two sets of arc-shaped clamping blocks 12 to clamp and fix the two sides of the drive shaft body 13. This allows the drive shaft body 13 to be well clamped and fixed before drilling, improving the clamping stability of the drilling device for drive shaft production and enabling the drive shaft to be drilled stably.

[0022] Specifically, the drive mechanism 14 is a motor located outside the base 1. The output end of the motor passes through the interior of the base 1 and is connected to the end of the rotating shaft 8 to drive the rotating shaft 8 to rotate inside the cavity 7. The motor is a forward and reverse rotating motor.

[0023] like Figure 1 As shown, support legs 17 are provided at the four corners of the bottom of the base 1. The support legs 17 are used to support and fix the base 1.

[0024] like Figure 2 and Figure 3 As shown, a drawer 15 is provided on one side of the base 1, and the drawer 15 is located inside the cavity 7.

[0025] Specifically, the inner side of the arc-shaped clamping block 12 is provided with an anti-slip pad (not marked in the figure), which enables the arc-shaped clamping block 12 to tightly clamp the drive shaft body 13.

[0026] Specifically, at least three drilling machines 6 are installed.

[0027] Working principle: In use, the drive shaft body 13 is initially positioned by placing it on the arc-shaped support 18. Then, the drive mechanism 14 rotates the shaft 8. When the shaft 8 rotates, the threaded sliders 9 on the threaded section 16 move towards each other. The limiting effect between the mortise bracket 10 and the through groove 11 prevents the threaded sliders 9 from rotating with the shaft 8. The movement of the threaded sliders 9 towards each other drives the mortise bracket 10 to move towards each other. The movement of the mortise bracket 10 towards each other drives the two sets of arc-shaped clamping blocks 12 to clamp and fix the two sides of the drive shaft body 13. This allows the drive shaft body 13 to be well clamped and fixed before drilling, improving the clamping stability of the drilling device for drive shaft production and enabling the drive shaft to be drilled stably.
