Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a drilling mechanism with adjustable dimensions. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, has a frame that acts like the skeleton of a person, allowing various bicycle parts to be mounted. The frame is made of materials such as iron and aluminum alloy, and the length and angles of the tubing affect the overall characteristics of the bicycle.

[0003] Patent (CN222036867U) discloses a punching device for bicycle manufacturing, including a base. A housing is fixedly connected to the middle of the base, and a processing component is slidably connected to the bottom of the housing. A shell is fixedly connected to the rear side of the housing. A gear is rotatably connected inside the shell, and two racks are slidably connected inside the shell, each rack meshing with the gear. L-shaped connecting plates are fixedly connected to the outer sides of each rack, and a clamping plate is fixedly connected to the other side of each L-shaped connecting plate. The L-shaped connecting plate is slidably connected to the middle of the shell and the base. A drive component is fixedly connected inside the shell. In this invention, the drive motor allows the clamping plate to hold the frame components without obstructing the placement of the frame components, thus enabling the clamping of frame components of different sizes.

[0004] Since bicycle frames are mainly composed of various welded tubing, and holes need to be drilled in these tubing for the subsequent installation of bicycle parts, the drilling equipment used in the aforementioned patent for bicycle production only clamps and fixes the frame. Each clamping and fixing operation can only perform one drilling operation on the frame surface. However, multiple drilling operations are required on multiple tubing of the frame. In other words, to complete the drilling operation on the frame, the drilling equipment in the aforementioned patent needs to readjust the angle and position of the frame after each hole is drilled before proceeding to the next drilling operation, which is too cumbersome. Even when drilling holes in unwelded frame tubing, the angle and position of the frame still need to be readjusted after each hole is drilled before proceeding to the next drilling operation, which is also too cumbersome.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable-size punching mechanism, including a support frame, a punching mechanism at one end of the top of the support frame, a conveying frame at the other end of the top of the conveying frame, the conveying frame including two support plates, the support plates being slidably connected to the top of the support frame, synchronous belt drive assemblies being symmetrically arranged on adjacent sides of the top of the two support plates, cylinders being symmetrically arranged at both ends of the top of the outer wall of the support plates, a support bar being provided at the bottom of the end of the cylinder away from the support plate, and the support bar being fixedly connected to the top of the outer wall of the support frame.

[0010] Furthermore, the top of the support frame is provided with several rotatably connected support shafts below the conveyor frame, and guide wheels are symmetrically provided on both sides of the outer wall of the support shafts.

[0011] Furthermore, the guide wheel has a frustum-shaped structure, and the outer diameter of the guide wheel gradually increases outward from the center of the support shaft.

[0012] Furthermore, the drilling mechanism includes a top plate and an adjusting plate. The top plate is fixedly connected to the support frame by several vertically arranged support rods.

[0015] 1. This utility model comprises a support frame, a drilling mechanism, a conveyor frame, a support plate, a synchronous belt drive assembly, and a cylinder. The conveyor frame is used to transport the pipe material to the area below the drilling mechanism, allowing for linear transport of the pipe material below the drilling mechanism. This facilitates continuous and multiple drilling operations on the pipe surface, making the process convenient and fast. The support plate in the conveyor frame supports the synchronous belt drive assembly. The two synchronous belt drive assemblies are used to clamp the outer walls of the pipe material on both sides, and simultaneously drive the pipe material to be transported on top of the support frame. By adjusting the cylinder's extension and retraction, the position of the support plate can be adjusted. As the support plate moves, the distance between the two synchronous belt drive assemblies can be adjusted, thus facilitating the clamping and transport of pipe materials of different sizes.

The first servo motor is used to drive one synchronous pulley to rotate, thereby driving the synchronous belt to rotate. The synchronous belt is tightly clamped to the surface of the pipe. The synchronous belt and the surface of the pipe are clamped in a strip-shaped structure on one side, with a larger clamping contact area, which can effectively improve the safety and stability of clamping and conveying the pipe. The two guide wheels on the outer wall of the support shaft provide rolling guidance and support for the pipe, which can further improve the safety and stability of pipe conveying.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: an adjustable-size punching mechanism, including a support frame 1, a punching mechanism 2 at one top end of the support frame 1, and a conveyor frame 3 at the other top end of the conveyor frame 1. The conveyor frame 3 includes two support plates 301, which are slidably connected to the top of the support frame 1. A synchronous belt drive assembly 302 is symmetrically arranged on adjacent sides of the top of the two support plates 301. Cylinders 303 are symmetrically arranged at both ends of the top of the outer wall of the support plate 301. A support bar 304 is provided at the bottom of the end of the cylinder 303 away from the support plate 301, and the support bar 304 is fixedly connected to the top of the outer wall of the support frame 1. The synchronous belt drive assembly 302... The moving assembly 302 includes a synchronous belt 305, a first servo motor 307, and two synchronous pulleys 306. The bottom of the synchronous pulleys 306 is rotatably connected to the top of the support plate 301. The synchronous belt 305 is movably fitted onto the outside of the two synchronous pulleys 306. The output shaft of the first servo motor 307 is fixedly connected to the top of one of the synchronous pulleys 306. The top of the support frame 1 is provided with several rotatably connected support shafts 103 below the conveyor frame 3. Guide wheels 104 are symmetrically provided on both sides of the outer wall of the support shafts 103. The guide wheels 104 have a frustum-shaped structure, and the outer diameter of the guide wheels 104 gradually increases outward from the center of the support shafts 103.

[0025] In one embodiment, the top of the support plate 301 is provided with a support frame 308 that is rotatably connected to the synchronous wheel 306. The first servo motor 307 is located on the top of the support frame 308. The support frame 308 provides a support frame for the synchronous wheel 306 to rotate on the top of the support plate 301. The first servo motor 307 drives the synchronous wheel 306 to rotate on the top of the support frame 308.

[0026] In one embodiment, the top of the support frame 1 is provided with a guide rail 101 below the support plate 301, and the bottom of the support plate 301 is provided with a plurality of sliders 102 that match the guide rail 101. The guide rail 101 guides the horizontal movement of the support plate 301 at the top of the support frame 1, which can effectively improve the safety and stability of the horizontal movement of the support plate 301. The support plate 301 is slidably connected to the guide rail 101 through the sliders 102. When the support plate 301 moves, the sliders 102 slide along the guide rail 101. By setting at least two sliders on a guide rail 101, the range of movement of the support plate 301 is increased, which can effectively avoid the guide rail 101 restricting the range of movement of the support plate 301, and ensure that the support plate 301 can drive the synchronous belt drive assembly 302 to move to the center of the top of the support frame 1. At the same time, it can prevent the guide rail 101 from extending into the pipe conveying channel at the top of the support frame 1, thereby avoiding friction damage between the guide rail 101 and the pipe.

[0027] In one embodiment, the drilling mechanism 2 includes a top plate 201 and an adjusting plate 203. The top plate 201 is fixedly connected to a support frame 1 via several vertically arranged support rods 202. The adjusting plate 203 is located below the top plate 201. Several servo electric cylinders 204 are arranged between the adjusting plate 203 and the top plate 201. A second servo motor 205 is provided at the top of the adjusting plate 203. A drill bit 206 is provided below the output shaft of the servo motor 205 at the bottom of the adjusting plate 203. The support rods 202 support the top plate 201. 01. The adjustment plate 203 provides overhead support for the second servo motor 205 and the drill bit 206. The extension and retraction of the servo cylinder 204 can drive the adjustment plate 203 to rise and fall, thereby driving the drill bit 206 to rise and fall. When the drilling mechanism 2 is working, the second servo motor 205 is turned on, the drill bit 206 rotates, and the adjustment servo cylinder 204 moves in extension and retraction. The servo cylinder 204 drives the drill bit 206 to rise and fall through the adjustment plate 203, and the drill bit 206 performs drilling operations on the bicycle frame tubes.

[0028] In one embodiment, the outer wall of the adjusting plate 203 is provided with a plurality of linear bearings 207 that are slidably connected to the support rod 202. The adjusting plate 203 can move up and down along the support rod 202 through the linear bearings 207. The support rod limits and guides the up and down movement of the adjusting rod 203, which can effectively improve the stability of the up and down movement of the adjusting plate 203, thereby improving the safety and stability of the up and down movement of the drill bit 206.

[0029] The working principle of this utility model:

[0030] Refer to the instruction manual appendix Figures 1-4This utility model comprises a support frame 1, a drilling mechanism 2, a conveyor frame 3, a support plate 301, a synchronous belt drive assembly 302, and a cylinder 303. The support frame 1 supports the drilling mechanism 2 and the conveyor frame 3. The drilling mechanism 2 is used to drill holes in the tubing used for bicycle frames. The conveyor frame 3 is used to convey the tubing to a position below the drilling mechanism 2. The tubing can be conveyed linearly below the drilling mechanism 2, facilitating continuous and multiple drilling operations on the surface of the tubing, which is convenient and quick. The support plate 3... The support plate 301 supports the synchronous belt drive assembly 302; the two synchronous belt drive assemblies 302 are used to clamp the outer walls of the pipe, and at the same time, the synchronous belt drive assembly 302 can drive the pipe to be transported on the top of the support frame 1; by adjusting the cylinder 303 to extend and retract, the position of the support plate 301 can be adjusted, and the synchronous belt drive assembly 302 moves with the support plate 301, so that the distance between the two synchronous belt drive assemblies 302 can be adjusted, thereby facilitating the clamping and transport of pipes of different sizes;

[0031] The two synchronous pulleys 306 in the synchronous belt drive assembly 302 are used to support the rotational motion of the synchronous belt 305. The first servo motor 307 drives one of the synchronous pulleys 306 to rotate, thereby driving the synchronous belt 305 to rotate. The synchronous belt 305 is tightly clamped to the surface of the pipe. The synchronous belt 305 and one side of the pipe surface have a strip-shaped structure for tight clamping, which increases the clamping contact area and effectively improves the safety and stability of clamping and conveying the pipe. The two synchronous belts 305 located on both sides of the pipe need to be set to rotate in opposite directions to ensure that the two synchronous belts 305 drive the pipe to be conveyed in the same direction, making the operation convenient and quick.

[0032] During the pipe drilling operation, the pipe is placed on top of the support frame 1. Two synchronous belt drive components 302 clamp and transport the pipe from both sides of its outer wall, and the bottom of the pipe rolls into contact with the guide wheels 104 on the outer wall of the support shaft 103. During the pipe transport process, the support shaft 103 rotates on top of the support frame 1, and the two guide wheels 104 on the outer wall of the support shaft 103 provide rolling guidance and support for the pipe, which can further improve the safety and stability of the pipe transport. The guide wheels 104 are designed as frustum-shaped structures, and the outer diameter of the guide wheels 104 gradually increases outward from the center of the support shaft 103, so that the two guide wheels 104 on the outer wall of the support shaft 103 form a trapezoidal channel at the center of the support shaft 103, which facilitates rolling guidance and support for pipes of different diameters, and can further improve the safety and stability of the pipe support.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
