Description

Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a fixture base for a hole punching machine. Background Technology

[0002] In the woodworking, decoration, construction, and landscaping industries, there is a widespread demand for on-site machining of structures such as slotted holes, square holes, tenons, mortises, and grooves. Although some workpieces have already had their holes and grooves machined before leaving the factory, on-site drilling and grooving can better adapt to the actual installation environment and effectively avoid material waste caused by mismatches in pre-processed dimensions.

[0003] The applicant disclosed a hole-opening machine in patent publication number CN211967794U, including a hole-opening device and a motor that provides power for the rotation of the hole-opening device. It also includes a clamping device connected to the hole-opening device via a support rod, allowing the hole-opening device to reciprocate relative to the clamping device along a certain trajectory according to the support rod. The hole-opening device is an interlaced chain structure formed by multiple chain plates hinged together in pairs via pins. Cutting tools with their blades facing the direction of chain rotation are fixedly mounted on the chain plates. This utility model places the cutting tools on the chain plates, which are hinged together to form a chain. The rotation of the chain completes the cutting action on the workpiece, making it suitable for processing slotted holes, square holes, tenons, mortises, grooves, and so on. The clamping device ensures processing stability. The equipment is easy to disassemble and maintain, has a simple and compact structure, and is suitable for various occasions such as construction sites and factories. As can be seen from the patent above, although this hole-making machine can meet the needs of processing strip holes, square holes, tenons, mortises, slots, and grooves, the applicant found in long-term use that the machine's left and right clamping surfaces are both beveled, making it difficult to process holes in rectangular timber, thus limiting its application range and reducing its flexibility. Furthermore, after the machine is clamped and fixed to the timber by the left and right clamping parts, the position of the cutting tool cannot be adjusted according to the required hole location. Based on these findings, the applicant has made further optimizations and improvements to this hole-making machine. Utility Model Content

[0004] The main purpose of this utility model is to provide a clamping base for a hole-opening machine, which aims to solve the problems that existing hole-opening machines are difficult to apply to the hole-opening processing of wood of different shapes, which limits the scope of use, reduces the flexibility of use, and makes it impossible to adjust the position of the cutter according to the hole to be processed.

[0005] To achieve the above objectives, this utility model provides a fixture base for a hole punching machine, including a fixed base and at least one movable base. The fixed base has a through hole through which the cutting tool of the hole punching machine passes, and a positioning scale is provided at the through hole. Support rods are respectively provided on both sides of the fixed base, and the fixed base is movably mounted on the support rods. The movable base is detachably mounted on the two support rods and can move in a limited direction toward or away from the fixed base.

[0006] Preferably, the movable seat includes a connecting part and a clamping part for abutting against the wood. Two protrusions are formed on the top surface of the connecting part. Each of the two protrusions has a through hole for the support rod to pass through, and each of the two protrusions is provided with a locking member for fixing the connecting part.

[0007] Preferably, a boss is formed on the top surface of the connecting part corresponding to the positions of the two support rods, and the two bosses are respectively spaced apart from the two protrusions; anti-slip texture is formed on the clamping part.

[0008] Preferably, a plurality of support ribs are formed between the connecting portion and the clamping portion, and the plurality of support ribs are evenly and spaced apart along the width direction of the connecting portion.

[0009] Preferably, the clamping part and the connecting part are perpendicular to each other.

[0010] Preferably, the clamping portion is inclined away from the connecting portion in a direction away from the fixing base.

[0011] Preferably, the hole-opening machine is provided with a guide rail vertically, characterized in that a positioning block is provided at the through hole to slide and engage with the guide rail; a plurality of bubble generators are provided on both sides of the through hole, and the plurality of bubble generators are spaced apart along the length and width directions of the base.

[0012] Preferably, the two support rods are provided with scales along their respective extension directions; the fixing base has mounting holes on both opposite sides for the support rods to pass through; and the fixing base is provided with a number of fasteners at intervals corresponding to the positions of the support rods.

[0013] Beneficial effects: 1. The fixture base of the hole-opening machine of this utility model has a positioning scale at the through hole. When the operator installs the fixing base onto the surface of the wood to be processed, the positioning scale can be aligned with the actual processing hole position, thereby ensuring the accuracy of the tool position when opening the hole, achieving precise positioning of the hole opening position, and making it reliable in use.

[0014] 2. The fixture base of this utility model for a hole-opening machine allows the operator to flexibly adjust the installation position of the movable seat according to the actual size of the wood to abut against the side wall of the wood and achieve the positioning of the fixed seat. This not only prevents the fixed seat from causing the tool to move randomly during the hole-opening process, effectively suppresses the vibration or displacement of the tool during the hole-opening process, and ensures the hole-opening accuracy, but is also suitable for wood of different sizes and has a wide range of applications.

[0015] 3. In the use of the clamping base of the hole-drilling machine of this utility model, the operator can flexibly adjust the fixed base according to the actual position of the hole to be drilled in the wood, and adjust the installation position of the hole-drilling machine tool in a synchronous manner. This enables hole-drilling operations at different positions on the surface of the wood to be processed, without the need to repeatedly clamp the wood. This not only simplifies the operation steps and improves the processing efficiency, but also expands the processing range.

[0016] 4. In the use of the clamping base of the hole-opening machine of this utility model, the operator can select the movable seat that matches the shape of the wood to be processed according to the actual needs. This can not only ensure effective contact between the movable seat and the wood and ensure stable clamping of the wood, but also improve the installation stability of the fixed seat and ensure the hole-opening accuracy of the tool. Furthermore, by changing different movable seats, the hole-opening requirements of wood with different shapes can be met, thus expanding the scope of application and improving the applicability to processing different types of wood.

[0026] Example 1: This utility model proposes a fixture base for a hole punching machine.

[0027] In one embodiment of this utility model, a fixture base for a hole punching machine includes a fixed base 1 and at least one movable base 2. The fixed base 1 has a through hole 3 for the cutting tool of the hole punching machine to pass through, and a positioning scale 4 is provided at the through hole 3. Support rods 5 are respectively provided on both sides of the fixed base 1, and the fixed base 1 is movably mounted on the support rods 5. The movable base 2 is detachably mounted on the two support rods 5 and can move in a limited direction toward or away from the fixed base 1.

[0028] It should be noted that the hole-opening machine may be the one disclosed in the applicant's patent with publication number CN211967794U; its specific working principle and structural composition will not be elaborated here. Specifically, such as... Figures 1 to 6 As shown, in the use of the fixture base of the hole-opening machine of this utility model, since a positioning scale 4 is set at the through hole 3, the operator can align the positioning scale 4 with the actual processing hole position when installing the fixing base 1 onto the surface of the wood to be processed, thereby ensuring the accuracy of the tool's position when opening the hole, achieving precise positioning of the hole opening position, and making it reliable in use.

[0029] Furthermore, since support rods 5 are respectively inserted on both sides of the fixed seat 1, and at least one movable seat 2 is detachably installed on the two support rods 5, the movable seat 2 and the support rods 5 can be detachably installed by means of sliding snap-fit, that is, the movable seat 2 is inserted on the support rods 5 and can be snap-fitted and fixed by means of fasteners or other connecting parts, so that the movable seat 2 can move and limit its movement in the direction of approaching or moving away from the fixed seat 1. The structural design is simple and reasonable. Moreover, the workers can flexibly adjust the installation position of the movable seat 2 according to the actual size of the wood so that it abuts against the side wall of the wood and realizes the positioning of the fixed seat 1. This not only prevents the fixed seat 1 from driving the tool to move randomly during the drilling process, but also effectively suppresses the vibration or displacement of the tool during the drilling process, ensuring drilling accuracy. It is also suitable for wood of different sizes and has a wide range of applications.

[0030] Understandably, during use, the clamping base of the hole-drilling machine of this utility model allows the operator to securely clamp the movable seat 2 and the support rod 5 together using fasteners or other connecting parts, thus achieving the clamping and limiting of the two support rods 5. Since the two support rods 5 are respectively inserted into the fixed seat 1, and the fixed seat 1 is movably mounted on the support rods 5, the fixed seat 1 can move relative to the movable seat 2 along the extension direction of the support rods 5. Simultaneously, the fixed seat 1 can be fixed on the support rods 5 using a wrench with a stud, as is common in the prior art. This allows the operator to flexibly adjust the fixed seat 1 according to the actual position of the hole to be drilled in the wood, and simultaneously adjust the installation position of the hole-drilling machine's cutting tool. This enables hole-drilling operations at different positions on the surface of the wood to be processed without repeatedly clamping the wood, simplifying the operation steps, improving processing efficiency, and expanding the processing range. In addition, workers can install two movable seats 2 on the support rod 5, with the two movable seats 2 located on opposite sides of the fixed seat 1, so as to achieve bidirectional clamping of the wood and further improve the installation stability of the fixed seat 1 and the positional accuracy of the hole punching machine tool.

[0031] It is worth noting that since the movable seat 2 is detachably installed on the two support rods 5, the operator can select the movable seat 2 that matches the shape of the wood to be processed according to the actual needs. For example, if the wood to be drilled is rectangular, the operator can select the movable seat 2 with the contact surface perpendicular to the fixed seat 1; if the wood to be drilled is round, the operator can select the movable seat 2 with the contact surface inclined to the fixed seat 1. This ensures effective contact between the movable seat 2 and the wood, ensuring stable clamping of the wood, and also improves the installation stability of the fixed seat 1, ensuring the drilling accuracy of the tool on the wood. Furthermore, by replacing different movable seats 2, the drilling needs of wood with different shapes can be met, expanding the scope of application and improving the applicability to processing different types of wood.

[0032] In one embodiment, the movable seat 2 includes a connecting portion 6 and a clamping portion 7 for abutting against the wood to be processed. Two protrusions 8 are formed on the top surface of the connecting portion 6. Each protrusion 8 has a through hole for the support rod 5 to pass through, and each protrusion 8 is provided with a locking member 9 for fixing the connecting portion 6. Specifically, as shown... Figures 1 to 6 As shown, the two protrusions 8 on the connecting part 6 enable the support rod 5 to be fixed at two points after passing through the hole, thereby preventing the movable seat 2 from deflecting due to single-point fixing and effectively enhancing the installation stability of the movable seat 2 on the support rod 5. The structural design is simple and reasonable. Furthermore, the locking element 9 provided on the protrusion 8 can be a rotary handle with a stud, which allows the operator to rotate the handle to quickly tighten or loosen the support rod 5. This facilitates the operator to flexibly adjust the installation position of the movable seat 2 according to the size of the wood and lock it securely.

[0033] In one embodiment, a boss 10 is formed on the top surface of the connecting part 6 corresponding to the positions of the two support rods 5, and the two bosses 10 are respectively spaced apart from the two protrusions 8; anti-slip texture is formed on the clamping part 7. Specifically, as shown in the figure Figures 1 to 6 As shown, the boss 10 can cooperate with the protrusion 8 to provide multi-point support for the connecting part 6, thereby preventing the connecting part 6 from tilting or deforming due to unilateral force, and ensuring the stability of the movable seat 2 on the support rod 5. Furthermore, the anti-slip texture on the clamping part 7 can increase the coefficient of friction with the wood surface, which can prevent relative sliding between the wood and the movable seat 2 during processing and affect the drilling accuracy, and can also adapt to the surface smoothness of certain woods or special shapes with curvature, so as to ensure reliable clamping force under various working conditions.

[0034] In one embodiment, a plurality of support ribs 11 are formed between the connecting portion 6 and the clamping portion 7, and the plurality of support ribs 11 are evenly and spaced apart along the width direction of the connecting portion 6. Specifically, as shown in the figure... Figure 1 , Figure 2 and Figure 6 As shown, a stable multi-point support structure can be formed between the connecting part 6 and the clamping part 7 through a number of support ribs 11, thereby effectively improving the structural strength of the movable seat 2 and preventing the clamping part 7 from being deformed due to force, thus affecting the clamping accuracy. The structural design is simple and reasonable.

[0035] In one embodiment, such as Figures 1 to 3 As shown, the clamping part 7 and the connecting part 6 are perpendicular to each other. Understandably, when it is necessary to process rectangular timber, the operator can use the movable seat 2, which is perpendicular to the connecting part 6, so that the contact surface of the clamping part 7 can stably fit against the side wall of the rectangular timber, thereby greatly increasing the effective clamping area, ensuring the uniform distribution of clamping force, and ensuring the clamping stability of the timber.

[0036] In one embodiment, such as Figures 3 to 6 As shown, the clamping part 7 is inclined away from the connecting part 6 in a direction away from the fixed seat 1. Understandably, when it is necessary to process round wood, the operator can select the movable seat 2, which is inclined away from the fixed seat 1 in the connecting part 6, so that the contact surface of the clamping part 7 can be stably attached to the outer wall of the round wood, thereby increasing the effective clamping area, ensuring the uniform distribution of clamping force, and ensuring the clamping stability of the wood.

[0037] In one embodiment, a guide rail 12 is vertically arranged on the hole punching machine, and a positioning block 13 is provided at the through hole 3 to slide and engage with the guide rail 12; a plurality of bubble generators 14 are respectively arranged on both sides of the through hole 3, and the plurality of bubble generators 14 are spaced apart along the length and width directions of the base. Specifically, as shown in the figure Figure 4 and Figure 5As shown, the sliding contact between the guide rail 12 and the positioning block 13 ensures that the drilling machine remains perpendicular to the surface of the wood being processed when the cutting tool is fed to drill a hole. This ensures the straightness of the cutting tool's feed direction and prevents the processed hole or groove from tilting, making it reliable in use. Furthermore, the multi-directional bubble meter 14 installed on both sides of the through hole 3 can monitor the horizontal state of the fixed seat 1 in real time, which helps the operator to quickly and accurately level the fixed seat 1 and effectively eliminates the drilling deviation caused by the tilt of the fixed seat 1 during installation.

[0038] In one embodiment, the two support rods 5 are provided with graduations 15 along their respective extension directions; mounting holes 16 for the support rods 5 to pass through are provided on both opposite sides of the fixing base 1; and a plurality of fasteners 17 are provided on the fixing base 1 at intervals corresponding to the positions of the support rods 5. Specifically, as shown in the figure... Figure 1 and Figure 5 As shown, the scale 15 provides an intuitive quantitative reference for adjusting the position of the movable seat 2, facilitating precise adjustment of the distance between the fixed seat 1 and the movable seat 2 by the operator. Furthermore, since mounting holes 16 for the support rods 5 to pass through are provided on both opposite sides of the fixed seat 1, the operator can adjust the installation positions of the two support rods 5 and the movable seat 2 according to the actual wood being processed, making it convenient and flexible to use. In addition, several fasteners 17 can provide multi-point clamping and limiting of the fixed seat 1 and the support rods 5, ensuring the stability of the fixed seat 1 after it has been moved and adjusted to the correct position on the support rods 5.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
