Description

Technical Field

[0001] This utility model relates to the field of CNC drilling machine equipment technology, and in particular to a six-sided drilling feeding mechanism. Background Technology

[0002] In six-sided drilling machines used in the furniture industry, the stability of the particleboard feeding process is crucial to drilling accuracy. In existing technology, the fixed rollers on the servo stop are rigidly fixed to the aluminum profile with bolts. When the board is pushed into the clamp assembly's reference surface, the fixed rollers contact the board in a hard-on-hard manner. Due to the lack of a buffer mechanism, the fixed rollers are prone to positional displacement under the impact force during long-term, frequent clamping of the board, making it difficult for multiple sets of fixed rollers to maintain the same reference line. Simultaneously, the connecting bolts are prone to loosening or even falling off due to continuous impact force, resulting in unstable positioning of the particleboard when it enters the six-sided drill. This instability directly leads to deviations in the drilling position, affecting the board processing accuracy and production efficiency. Utility Model Content

[0003] This utility model provides a six-sided drilling feeding mechanism, which is used to solve the problem that the clamping wheel is in contact with the plate in a hard-on manner and is prone to positional displacement due to impact force.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A six-sided drilling feeding mechanism includes a roller assembly mounted on a frame. One end of the roller assembly is provided with a positioning reference surface. The mechanism also includes a driving device located at the other end of the roller assembly. The output end of the driving device is connected to a support member located above the roller assembly. The driving device drives the support member to move in a direction close to or away from the positioning reference surface. The end face of the support member close to the positioning reference surface is a first end face, and the support member is slidably connected to at least one sliding lug for pushing a side plate. The sliding direction of each sliding lug is consistent with the driving direction of the driving device. The end face of each sliding lug close to the positioning reference surface is located outside the first end face. A buffer space is formed between the end of the sliding lug away from the positioning reference surface and the support member. A buffer assembly is installed in the buffer space. The support member also has a limiting member for limiting excessive sliding of the sliding lug.

[0006] Furthermore, each of the sliding ear plates is provided with a sliding groove along its sliding direction, and the bearing member is slidably installed in each of the sliding grooves.

[0007] Furthermore, the support member includes a profile body that slides on the roller assembly, and a base that slides along the roller assembly. The first end of the base is connected to the frame, the second end of the base is connected to the profile body, and the base is driven by the drive device.

[0008] Furthermore, the buffer assembly includes a support member movable within the buffer space and an elastic member sleeved outside the support member, with both ends of the elastic member abutting against the bearing member and the sliding lug, respectively.

[0009] Furthermore, the first end of the support member is threadedly connected to the sliding lug plate, and the second end of the support member is movably inserted through the bearing member and connected to an adjusting member, the adjusting member abutting against the end of the bearing member away from the plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model proposes a six-sided drilling feeding mechanism, including a roller assembly mounted on a frame. The roller assembly has a positioning reference surface and a driving device at both ends. The output end of the driving device is connected to a support member located above the roller assembly. The end face of the support member closest to the positioning reference surface is the first end face. The support member is slidably connected to at least one sliding ear plate for pushing a plate. The driving device drives the support member and the sliding ear plate to push the plate towards the positioning reference surface. A buffer space is formed between the end of the sliding ear plate away from the plate and the support member. A buffer assembly is installed in the buffer space. During the process of the sliding ear plate pushing the plate, the sliding ear plate slides in the direction close to or away from the positioning reference surface due to the impact force from the plate. The buffer assembly in the buffer space absorbs the impact force, preventing rigid collision between the sliding ear plate and the plate. The support member is also provided with a limiting member to restrict excessive sliding of the sliding ear plate, effectively improving the stability of the plate feeding.

The present invention proposes a six-sided drilling feeding mechanism, wherein each sliding ear plate is provided with a sliding groove along its sliding direction, and can be slidably installed with the bearing member through each sliding groove.

[0016] 3. The present invention proposes a six-sided drilling feeding mechanism, wherein the bearing component includes a profile body that slides on the roller assembly and a base that slides along the roller assembly. The base is connected to the profile body and is connected to a driving device. By controlling the driving device, the movement of the bearing component on the roller assembly can be controlled to realize the pushing of the plate.

[0017] 4. The present invention proposes a six-sided drilling feeding mechanism, wherein the buffer assembly includes an elastic element and a support element.

Detailed Implementation

[0024] The following is combined Figures 1 to 3 This utility model will be described in detail.

[0025] A six-sided drilling feeding mechanism, such as Figure 1 As shown, the device includes a roller assembly (omitted in the figure) mounted on a frame. One end of the roller assembly has a positioning reference surface. The device also includes a drive device located at the other end of the roller assembly. The output end of the drive device is connected to a support member 20 located above the roller assembly. The drive device drives the support member 20 to move in a direction close to or away from the positioning reference surface. The end face of the support member 20 close to the positioning reference surface is the first end face. The support member 20 is slidably connected to at least one sliding ear plate 30 for side-pushing plate components. The sliding direction of each sliding ear plate 30 is consistent with the driving direction of the drive device. The end face of each sliding ear plate 30 close to the positioning reference surface is located outside the first end face. A buffer space is formed between the end of the sliding ear plate 30 away from the positioning reference surface and the support member 20. A buffer assembly 50 is installed in the buffer space. The support member 20 is also provided with a limiting member 40 for limiting the excessive sliding of the sliding ear plate 30.

[0026] The sliding direction of the sliding ear plate 30 is consistent with the driving direction of the driving device, meaning that the sliding ear plate 30 and the driving device move in the same axial direction. Specifically, the sliding direction of the sliding ear plate 30 and the driving direction of the driving device are both perpendicular to the feeding direction of the plate. During plate positioning, the control driving device drives the carrier 20 close to the positioning reference surface, and the sliding ear plate 30 abuts against the plate and pushes the plate into the positioning reference surface. During the pushing process, the impact force when the sliding ear plate 30 abuts against the plate causes the sliding ear plate 30 to slide relative to the carrier 20. The sliding direction of the sliding ear plate 30 is opposite to the moving direction of the carrier 20. The buffer component 50 in the buffer space absorbs the impact force, avoiding rigid collision between the sliding ear plate 30 and the plate, effectively improving the stability of the plate feeding.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, each sliding ear plate 30 is provided with a groove 301 along its sliding direction. The bearing member 20 is slidably installed in each groove 301. When the impact force of the buffer plate is applied, the sliding ear plate 30 slides in the opposite direction to the bearing member 20. One end of the limiting member 40 is installed in the bearing member 20, and the other end of the limiting member 40 moves in the groove 301. When the sliding distance of the sliding ear plate 30 is too large, the limiting member 40 abuts against the end of the groove 301 to limit the sliding of the sliding ear plate 30.

[0028] The support component 20 includes a profile body 201 that slides on the roller assembly, and a base that slides along the roller assembly. The first end of the base is connected to the frame via a guide rail pair, and the second end of the base is connected to the profile body 201. A drive device is connected to the base. A guide rail pair is located at the top of the frame, and the base is slidably connected to the frame via the guide rail pair. The roller assembly is mounted above the frame, and the guide rail pair is located below the roller assembly and does not contact it. The roller assembly includes several parallel rollers with gaps between adjacent rollers. The second end of the base passes through these gaps and connects to the profile body 201. A drive device is connected to the base, which drives the base to slide along the guide rail pair, simultaneously causing the profile body 201 to slide on the roller assembly. The drive device includes a servo motor connected to the base, which can be remotely controlled by signals. The sliding ear plate 30 can be movable on the top of the profile body 201 or slidably mounted on the side of the profile body 201.

[0029] In this embodiment, the sliding ear plate 30 is movable on the top of the profile body 201. The bearing member 20 also includes a sliding member 202 connected to the profile body 201. Several sets of mounting positions are sequentially provided along the axial direction of the top of the profile body 201. Several sliding members 202 corresponding to each sliding ear plate 30 are installed in each set of mounting positions, and each sliding member 202 is installed within the slide groove 301. Specifically, the sliding member 202 is fixed to the mounting position by bolts or other connecting members. The sliding ear plate 30 is fixed to the sliding member 202 by a limiting member 40 to prevent the sliding ear plate 30 from detaching from the sliding member 202. The slide groove 301 is an oblong hole, meaning that each corner of the slide groove 301 has a smooth transition treatment, avoiding stress concentration caused by sharp edges. A shim is provided between the sliding ear plate 30 and the bolt. The radial dimension of the shim is larger than the width of the slide groove 301. This ensures that the sliding ear plate 30 will not detach from the slide member 202 when it slides along the slide member 202, and also reduces wear at the connection between the bolt and the sliding ear plate 30. Several sets of mounting positions are several parallel slide rails 2011, each slide rail 2011 having a T-shaped cross-section. In other embodiments, the slide member 202 may also be slidably connected to the slide rail 2011.

[0030] The buffer assembly 50 includes a support member 501 movable within the buffer space and an elastic member 502 sleeved outside the support member 501. Both ends of the elastic member 502 abut against the bearing member 20 and the sliding ear plate 30, respectively. When the buffer plate experiences impact, at least one end of the support member extends into the bearing member 20 or the sliding ear plate 30, reducing the limiting space. The elastic member 502 is compressed under force, and the elastic force generated by the deformation of the elastic member 502 offsets the impact force from the collision of the plates, achieving buffer protection. The first end of the support member 501 is threadedly connected to the sliding ear plate 30, and the second end of the support member 501 is movably inserted through the bearing member 20 and connected to an adjusting member. The adjusting member abuts against the end of the bearing member 20 furthest from the plate. By rotating the support member 501, the distance between the sliding ear plate 30 and the bearing member 20 can be adjusted, thereby adjusting the size of the buffer space and controlling the preload of the elastic member 502, ensuring good buffering performance even after repeated use. During buffering, the sliding ear plate 30 slides under the impact force of the plate. Since the sliding ear plate 30 is threadedly fixed to the support rod, it pushes the adjusting member away from the bearing member 20. The elastic force generated by the deformation of the elastic member 502 absorbs the impact force. The bearing member 20 has a through hole that matches the second end of the support member 501, allowing the support member 501 to move within the through hole. The radial dimension of the adjusting member is larger than the radial dimension of the through hole, and the adjusting member abuts against the end of the bearing member 20 away from the plate for easy adjustment. The adjusting block and the support rod can be integrally formed or separately formed. In use, the preload of the elastic member 502 can be adjusted according to different needs, adjusting the position of the support member 501 in the sliding ear plate 30, thereby adjusting the position of the sliding ear plate 30 relative to the bearing member 20, so that each sliding ear plate 30 is on the same reference line, facilitating subsequent positioning of the plate.

[0031] The support member 20 also includes a fixing member 203. The first end of the fixing member 203 is detachably connected to the profile body 201 via bolts or other connecting parts, and the second end cooperates with the sliding ear plate 30 to form a buffer space. The two ends of the elastic member 502 abut against the sliding ear plate 30 and the fixing member 203 respectively. The fixing member 203 is provided with a through hole to facilitate adjustment of the size of the buffer space. The fixing member 203, the profile body 201, and the sliding member 202 are formed separately, which facilitates processing and production.

[0032] This embodiment also includes a clamping assembly 60. The clamping assembly 60 includes a guide rail 601 mounted on the frame, with its central axis aligned with the feeding direction of the roller assembly. The clamping assembly 60 also includes a clamping group 602 slidably connected to the guide rail 601. The clamping group 602 is movable at the top of the roller assembly, and a positioning reference surface is provided facing the workpiece. Specifically, the positioning reference surface is located at the clamping surface of the clamping group 602. During positioning, the sliding ear plate 30 pushes the workpiece into the positioning reference surface to complete the positioning, at which point one side of the workpiece abuts against the positioning reference surface. After positioning, the clamping group 602 clamps the workpiece and transfers it to the next processing station. The clamping group 602 is also electrically connected to a power supply device such as a motor, which can control the movement of the clamping group 602 on the guide rail 601 and whether the clamping group 602 clamps the workpiece.

[0033] The feed end of the roller assembly has a pusher 90, one end of which can reciprocate on the roller assembly to push the plate from the feed end to the output end. The frame is also equipped with a stop 70, located at the output end of the roller assembly. When the plate is pushed by the pusher 90 to the stop 70, the pusher 90 stops pushing and returns to its original position. The servo motor then drives the carrier 20 and the sliding ear plate 30 to complete the positioning. The end of the sliding ear plate 30 near the positioning reference surface is also equipped with a clamping wheel 302. The axial side of the clamping wheel 302 faces the plate, meaning that the arc-shaped side of the clamping wheel 302 can abut against the plate. This rolling contact reduces direct friction between the clamping wheel and the plate, avoiding scratches and damage to the plate surface.

[0034] The profile body 201 is made of original 4060 aluminum profile. Without altering the main frame of the equipment, its modular, flexible connection and adjustable design improve the stability of panel feeding, simplify installation and maintenance, effectively ensure the drilling accuracy of the six-sided drill, and significantly improve furniture production efficiency and product quality. In other embodiments, the profile body 201 can also be made of other materials or profile types. In furniture production, the panels are typically made of particleboard 80.

[0035] The working process of the six-sided drilling feeding mechanism proposed in this embodiment is as follows:

[0036] First, the particleboard 80 is transferred from the previous processing station to the roller assembly of the feeding conveyor by machine or manually. Then, the pusher 90 is controlled to push the particleboard 80 on the roller assembly until one end of the particleboard 80 abuts against the stop 70. The pusher 90 then stops pushing the particleboard 80, and the particleboard 80 is positioned. During positioning, the servo motor is activated remotely. After the servo motor starts, it drives the base to move towards the particleboard 80. The particleboard 80 is pushed to the positioning reference surface by the top clamping wheel 302. During the pushing process, the impact force generated by the top clamping wheel 302 contacting the particleboard 80 causes the sliding ear plate 30 to move along the sliding member 202, reducing the buffer space. The spring undergoes elastic deformation to effectively absorb the impact force and avoid rigid collision. After the particleboard 80 is pushed to the positioning reference surface, the spring returns to its original deformation and pushes the top clamping wheel 302 to continue to abut against the particleboard 80, preventing the particleboard 80 from losing its positioning effect under impact force. After positioning is completed, clamp assembly 602 clamps the particleboard 80 and transfers it to the next processing station.
