Description

Technical Field

[0001] This utility model relates to an auxiliary mechanism for drilling equipment for bamboo and wood components, specifically a workpiece positioning mechanism for drilling equipment for bamboo and wood components. Background Technology

[0002] Drilling is a common process in the processing of bamboo and wood components. Existing drilling equipment for bamboo and wood components generally includes a bamboo and wood component clamping mechanism and a drilling machine for drilling holes in the clamped bamboo and wood components. A corresponding drive mechanism drives the drilling machine to perform drilling operations on the bamboo and wood components according to a set path.

[0003] Existing bamboo and wood component clamping mechanisms are functionally limited, only capable of clamping the bamboo and wood components to prevent positional shifts during drilling. To ensure the drilling position of the bamboo and wood components does not deviate excessively, existing bamboo and wood component drilling equipment generally requires a corresponding correction mechanism. This correction mechanism is used to correct the incoming material, and then the clamping mechanism is used to clamp the corrected bamboo and wood components for subsequent drilling operations. However, the overall structure of the correction mechanism in existing bamboo and wood component drilling equipment is complex, resulting in relatively high equipment costs. Most importantly, the overall structure of the correction mechanism is not compact enough, making its installation between adjacent drilling machines relatively difficult.

[0004] Therefore, the research objective of this utility model is to design a workpiece positioning mechanism for drilling equipment of bamboo and wood components that is simple in structure, compact, and can combine clamping and straightening functions, thereby effectively reducing the manufacturing and operating costs of the equipment and facilitating the installation and use of the mechanism. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a workpiece positioning mechanism for a drilling equipment for bamboo and wood components, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A workpiece positioning mechanism for a drilling device for bamboo and wood components includes a drilling worktable and a clamping assembly disposed on the drilling worktable, the clamping assembly comprising:

[0008] A clamping cylinder is fixedly installed on the upper side of the drilling workbench. The piston rod end of the clamping cylinder is set downward. A corresponding inclined guide plate is inclinedly set on the front side of the clamping cylinder. A corresponding notch is set at the bottom end of the inclined guide plate. Insertion holes with polygonal cross sections are respectively provided through the inclined guide plates on both sides of the notch.

[0009] A set of plug-in shafts are movably plugged into corresponding plug-in holes. A mounting shaft with a circular cross-section is fixed between the plug-in shafts. A corresponding abutment roller is rotatably sleeved on the mounting shaft. A corresponding side support plate is provided on one side of the drilling worktable. The end of the plug-in shaft near the side support plate extends outward and is fixedly connected to a corresponding limiting plate. A corresponding buffer spring is fixedly installed between the limiting plate and the inclined guide plate. The end of the plug-in shaft away from the side support plate extends outward and is fixedly connected to a corresponding arc-shaped guide plate.

[0010] The mounting shaft is integrally formed and connected between the plug shafts, and the cross-sectional diameter of the mounting shaft is smaller than the inscribed circle diameter of the cross-section of the plug shaft.

[0011] The insertion shaft and the mounting shaft are hollowly connected, and a corresponding pressure sensor is fixedly installed at the bottom of the mounting shaft by an embedding method.

[0012] The abutting roller is made of rubber material, and a corresponding annular rigid side plate is fixed to the side of the abutting roller near the side support plate.

[0013] The annular rigid side plate is composed of a set of semi-annular plates, which are fixedly bonded to the side of the abutting roller by adhesive.

[0014] The piston rod end of the compression cylinder is positioned downwards and is fixedly connected to a corresponding rubber compression block.

[0015] The inclined guide plate is connected to the cylinder body of the clamping cylinder via corresponding connecting plates.

[0016] The side support plate is hollowed out with corresponding guide holes.

[0017] Advantages of this utility model:

[0018] 1) In this utility model, a corresponding inclined guide plate is inclinedly arranged on the front side of the clamping cylinder, and a notch is provided at the bottom end of the inclined guide plate. A polygonal cross-section insertion hole is provided through the inclined guide plate on both sides of the notch. Then, a set of insertion shafts are movably inserted into the corresponding insertion holes. An installation shaft for abutting roller sleeve is provided between the insertion shafts. Then, a side support plate is provided on one side of the drilling worktable. The end of the insertion shaft near the side support plate extends outward and is fixedly connected to a corresponding limiting plate. A buffer spring is fixedly installed between the limiting plate and the inclined guide plate. The end of the insertion shaft away from the side support plate extends outward and is fixedly connected to an arc-shaped guide plate.

[0019] During the process of the bamboo and wood components entering the drilling station, the abutment roller adjusts their longitudinal position to prevent excessive warping, while the arc-shaped guide plate corrects their horizontal position to prevent horizontal deviation. After the bamboo and wood components are in place, their position is simultaneously corrected. At this point, simply controlling the piston rod of the clamping cylinder to extend is enough to clamp the bamboo and wood components, facilitating the subsequent drilling process. This results in a simple and compact structure that combines clamping and correction functions, effectively reducing the manufacturing and operating costs of the equipment and simplifying its installation and use.

[0020] 2) The cross-sectional diameter of the mounting shaft of this utility model is smaller than the inscribed circle diameter of the plug-in shaft, and the abutting roller is made of rubber. During installation, the abutting roller can be pre-placed at the notch of the inclined guide plate, and the center hole of the abutting roller can be enlarged. Then, the buffer spring, plug-in shaft, mounting shaft, and other components are assembled into place. Finally, the arc-shaped guide plate is fixed in place, which is very convenient. This ensures both the structural simplicity and compact assembly of each component of this utility model, as well as its ease of assembly, thus effectively ensuring the practical effect of this utility model.

[0021] 3) The plug-in shaft and mounting shaft of this utility model are hollowly connected, and a corresponding pressure sensor is fixedly installed at the bottom of the mounting shaft by an embedding method. The abutting roller is made of rubber material, and a corresponding annular rigid side plate is fixedly connected to its side near the side support plate. When the bamboo or wood component is too tall, it will squeeze the abutting roller upward during the feeding process, thereby increasing the pressure value of the pressure sensor. When the bamboo or wood component is too wide, the arc-shaped guide plate is pushed outward by the bamboo or wood component, thereby driving the plug-in shaft to squeeze the annular rigid side plate horizontally, causing the abutting roller to be squeezed laterally and expand to the upper and lower sides, thereby increasing the pressure value of the pressure sensor. In this way, when the pressure value of the pressure sensor reaches the set value, it can be determined that the bamboo or wood component is too tall or too wide. At this time, the drilling mechanism does not start working, and the bamboo or wood component that exceeds the size limit can be directly screened out. This can save resources and effectively and timely screen out bamboo or wood components that exceed the size limit, thereby improving the qualification rate of bamboo or wood components entering the next process.

[0022] 4) The annular rigid side plate of this utility model is composed of a set of semi-annular plates, which are fixedly bonded to the side of the abutting roller by adhesive, so that the annular rigid side plate can be smoothly clamped between the abutting roller and the plane of the insertion shaft that extends beyond the mounting shaft, thereby further ensuring the practical effect of this utility model.

[0028] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0029] refer to Figure 1-4 A workpiece positioning mechanism for a drilling equipment for bamboo and wood components includes a drilling worktable 1 and a clamping assembly 2 disposed on the drilling worktable 1, the clamping assembly 2 comprising:

[0030] A clamping cylinder 201 is fixedly installed on the upper side of the drilling workbench 1. The piston rod end of the clamping cylinder 201 is set downward. A corresponding inclined guide plate 202 is inclinedly arranged on the front side of the clamping cylinder 201. A corresponding notch is provided at the bottom end of the inclined guide plate 202. Insertion holes with polygonal cross sections are respectively provided on the inclined guide plates 202 on both sides of the notch.

[0031] A set of plug-in shafts 203 are movably plugged into corresponding plug-in holes. A mounting shaft 204 with a circular cross-section is fixedly connected between the plug-in shafts 203. A corresponding abutment roller 205 is rotatably sleeved on the mounting shaft 204. A corresponding side support plate 206 is provided on one side of the drilling workbench 1. The end of the plug-in shaft 203 on the side close to the side support plate 206 extends outward and is fixedly connected to a corresponding limiting plate 207. A corresponding buffer spring 208 is fixedly installed between the limiting plate 207 and the inclined guide plate 202. The end of the plug-in shaft 203 on the side away from the side support plate 206 extends outward and is fixedly connected to a corresponding arc-shaped guide plate 209.

[0032] During the process of the bamboo and wood components entering the drilling station, the abutment roller 205 adjusts their longitudinal position to prevent excessive warping, while the arc-shaped guide plate 209 corrects their horizontal position to prevent horizontal deviation. After the bamboo and wood components are in place, their position correction is completed simultaneously. At this point, simply controlling the piston rod end of the clamping cylinder 201 to extend can clamp the bamboo and wood components, facilitating the subsequent drilling process. This achieves a simple and compact structure that combines clamping and correction functions, effectively reducing the manufacturing and operating costs of the equipment and facilitating its installation and use.

[0033] The mounting shaft 204 is integrally formed and connected to the insertion shaft 203, and the cross-sectional diameter of the mounting shaft 204 is smaller than the inscribed circle diameter of the insertion shaft 203. The insertion shaft 203 and the mounting shaft 204 are hollowly connected, and a corresponding pressure sensor 3 is fixedly installed at the bottom of the mounting shaft 204 by an embedding method. The abutting roller 205 is made of rubber material, and a corresponding annular rigid side plate 4 is fixedly connected to the side of the abutting roller 205 near the side support plate 206.

[0034] During installation, the abutting roller 205 can be pre-placed at the notch of the inclined guide plate 202, and the center hole of the abutting roller 205 can be enlarged. Then, the buffer spring 208, the insertion shaft 203, the mounting shaft 204, and other components can be assembled into place. Finally, the arc-shaped guide plate 209 can be fixed in place, which is very convenient. This ensures the simplicity of the structure and the compactness of the assembly of each component of the present invention, as well as its ease of assembly, thereby effectively ensuring the practical effect of the present invention.

[0035] The present invention features a hollow, interconnected insertion shaft 203 and mounting shaft 204. A pressure sensor 3 is fixedly mounted at the bottom of the mounting shaft 204 via an embedded method. The abutment roller 205 is made of rubber, and a corresponding annular rigid side plate 4 is fixedly attached to its side near the side support plate 206. When the bamboo / wood component is too tall, its feeding process will exert upward pressure on the abutment roller 205, thus increasing the pressure value of the pressure sensor 3. When the bamboo / wood component is too wide, the arc-shaped guide plate 209 is pushed outward by the component, causing the insertion shaft 203 to exert horizontal pressure on the annular rigid side plate 4. This causes the abutment roller 205 to expand laterally, increasing the pressure value of the pressure sensor 3. Thus, when the pressure value of the pressure sensor 3 reaches a set value, it can be determined whether the bamboo / wood component is too tall or too wide. At this point, the drilling mechanism does not need to be activated; the bamboo / wood component exceeding the size limit can be directly screened out. This not only saves resources but also effectively and promptly screens out bamboo and wood components that exceed size limits, thereby improving the pass rate of bamboo and wood components entering the next process.

[0036] The annular rigid side plate 4 is composed of a set of semi-annular plates, which are fixedly bonded to the side of the abutting roller 205 by adhesive. This allows the annular rigid side plate 4 to be smoothly clamped between the abutting roller 205 and the plane of the insertion shaft 203 that extends beyond the mounting shaft 204, thereby further ensuring the practical effect of this utility model.

[0037] The piston rod end of the clamping cylinder 201 is positioned downwards and is fixedly connected to a corresponding rubber pressure block 5. The inclined guide plate 202 is connected to the cylinder body of the clamping cylinder 201 via a corresponding connecting plate 6. The side support plate 206 is perforated with corresponding guide holes 7.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
