Description

Technical Field

[0001] This utility model belongs to the field of metal round rod processing technology, specifically relating to a device for drilling holes at the end of a metal round rod. Background Technology

[0002] Metal round rods are long strip-shaped metal profiles with a circular cross-section. They are widely used in the industrial field, serving as shaft parts in mechanical transmissions, supporting components in building structures, and basic raw materials for products such as furniture hardware, automotive parts, and medical devices. They are the core carriers for functions such as connection, transmission, and support.

[0003] Drilling holes at the end of a metal rod is a specialized machining process that involves drilling holes in the end face or the circumferential surface near the end face of the rod. Its core purpose is to provide an interface for subsequent assembly (such as bolt connections and pin mating) and functional expansion (such as fluid channels and cable runs).

[0004] Currently, traditional processing methods for drilling holes at the ends of metal rods have significant shortcomings: if the workpiece is manually held close to the part to be drilled, insufficient hand stability can easily cause the workpiece to tilt, leading to problems such as hole position deviation, hole diameter accuracy deviation, and rough hole opening, which seriously affects the drilling quality; if a fixed device is used to clamp the workpiece to improve stability, although it can improve drilling accuracy, after processing one end, the machine must be stopped, the workpiece disassembled, flipped and adjusted, and re-clamped before processing the other end. The operation process is cumbersome and time-consuming, which greatly extends the single processing cycle, resulting in low overall drilling efficiency and difficulty in meeting the needs of mass production. Utility Model Content

[0005] The purpose of this utility model is to provide a device for drilling holes at the end of a metal round rod, so as to solve the problems of poor processing quality due to manual hand-held drilling and low efficiency due to inconvenience in changing the end of the fixed device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal rod end drilling device, comprising a worktable, two connecting blocks connected to the top of the worktable, each of the two connecting blocks having a second groove on its side close to each other, a movable block movably disposed inside the second groove, a fixed block rotatably disposed between the two movable blocks, a third groove on the fixed block, a movable block disposed inside the third groove, a screw movably sleeved on one side of the movable block, the fixed block being threaded onto the screw, and a drilling component disposed on the top of the worktable away from the connecting blocks.

[0007] Furthermore, a slot No. 1 is provided on the top of the workbench, and two connecting blocks are symmetrically arranged on both sides of the slot No. 1.

[0008] Furthermore, a transverse rod is provided in the second groove, a movable block is slidably sleeved on the transverse rod, and an elastic element is sleeved on the transverse rod. The two ends of the elastic element respectively abut against the inner wall of the second groove and one side of the movable block.

[0009] Furthermore, the moving block comes into contact with the inner wall of the second slot.

[0010] Furthermore, each of the two movable blocks is connected to a connecting shaft on one side that is close to the other, and the two sides of the fixed block are respectively movably sleeved on the two connecting shafts at the ends that are close to each other.

[0011] Furthermore, both connecting shafts are fitted with torsion springs, with the two ends of the torsion springs respectively located on the moving block and the fixed block.

[0012] Furthermore, a horizontal plate is connected to one side of the two connecting blocks that are close to each other, and a notch is provided on the top of the horizontal plate.

[0013] Furthermore, the diameter of the screw near the movable block is greater than the diameter of the middle part of the screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This metal rod end drilling device, through the cooperation of a fixed block with a No. 3 groove and a movable block that can be driven by a screw, can stably clamp the metal rod to prevent tilting and ensure drilling accuracy. At the same time, the fixed block can rotate, so after processing one end, there is no need to disassemble the workpiece. Simply rotate the fixed block to switch to the other end. With the precise positioning of the horizontal plate notch, the end-changing operation is greatly simplified, taking into account both drilling quality and processing efficiency.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figure 1-6 This utility model provides a metal rod end drilling device, including a workbench 10, a first groove 101 is opened on the top of the workbench 10, and two connecting blocks 20 are connected to the top of the workbench 10, the two connecting blocks 20 are symmetrically located in the first groove 101.

[0026] Two connecting blocks 20 are provided with a second groove 201 on their sides that are close to each other. A transverse rod 210 is arranged in the two second grooves 201. A movable block 220 is sleeved on the transverse rod 210. Both the second groove 201 and the movable block 220 are rectangular, and the movable block 220 is in contact with the inner wall of the second groove 201, so that the movable block 220 cannot rotate in the second groove 201. An elastic element 230 is sleeved on the transverse rod 210. The two ends of the elastic element 230 abut against the inner wall of the second groove 201 and one side of the movable block 220, respectively. When the movable block 220 is subjected to force and moves in the direction of the elastic element 230, the movable block 220 compresses the elastic element 230 to store force. When the force on the movable block 220 is released, the movable block 220 moves back under the restoring force of the elastic element 230.

[0027] A fixed block 30 is rotatably disposed between two connecting blocks 20. A connecting shaft 221 is connected to one side of each of the two moving blocks 220 that are close to each other. The two sides of the fixed block 30 are respectively movably sleeved on the two ends of the connecting shaft 221 that are close to each other. A third groove 301 is opened on the fixed block 30, which is vertically through. A movable block 310 is disposed in the third groove 301. A screw 320 is movably sleeved on one side of the movable block 310. The fixed block 30 is threaded onto the screw 320. The diameter of the end of the screw 320 near the movable block 310 is larger than the diameter of the middle part of the screw 320, so that the movable block 310 will not rotate with the screw 320, but can be pulled or pushed by the screw 320. When a metal rod 40 is placed between the movable block 310 and the third groove 301, the screw 320 is rotated, and the screw 320 pushes the movable block 310 to clamp the metal rod 40.

[0028] Both connecting shafts 221 are fitted with torsion springs 222. The two ends of the torsion springs 222 are respectively set on the moving block 220 and the fixed block 30. When the fixed block 30 rotates with the connecting shaft 221 as the axis, the torsion springs 222 store force. After the fixed block 30 is free from external force, the fixed block 30 returns to its original state under the action of the torsion springs 222.

[0029] A punching component 50 is provided on the top side of the workbench 10 away from the connecting block 20. When the metal rod 40 is fixed by the movable block 310, the metal rod 40 and the punching component 50 are on the same plane. After the metal rod 40 rotates 90 degrees, the end of the metal rod 40 and the drill bit of the punching component 50 are on the same straight line.

[0030] A horizontal plate 240 is connected to one side of the two connecting blocks 20 that are close to each other. A notch 2401 is provided on the top of the horizontal plate 240. The notch 2401 is used to place the metal rod 40 and at the same time restrict the rotation angle of the metal rod 40 to ensure that the end of the metal rod 40 is on the same straight line as the drill bit of the drilling part 50.

[0031] The working principle and usage process of this utility model are as follows: Start the drilling part 50 on the workbench 10, place the metal rod 40 to be processed between the third slot 301 of the fixed block 30 and the movable block 310, rotate the screw 320. Because the diameter of the end of the screw 320 near the movable block 310 is larger than the diameter in the middle, the movable block 310 will not rotate with the screw 320, but will only be pushed by the screw 320 until the movable block 310 and the inner wall of the third slot 301 cooperate to clamp the metal rod 40.

[0032] After the fixed block 30 is moved a certain distance towards the drilling component 50, it is rotated clockwise or counterclockwise until the metal rod 40 contacts the notch 2401 on the transverse plate 240. At this time, the torsion spring 222 on the connecting shaft 221 stores force. The fixed block 30 is then moved towards the drilling component 50, and the drill bit of the drilling component 50 is used to drill a hole at the end of the metal rod 40. The actions of rotating the screw 320, pushing the fixed block 30, and rotating the fixed block 30 are all performed manually.

[0033] After the metal rod 40 is processed, the pushing force on the fixed block 30 is released, and the moving block 220 moves back under the restoring force of the elastic element 230. The rotational force on the fixed block 30 is released, and under the restoring force of the torsion spring 222, the fixed block 30 returns to its initial position. The fixed block 30 is rotated so that the unprocessed end of the metal rod 40 faces the punched part 50, and the above operation is repeated for processing.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
