Description

Technical Field

[0001] This application relates to the technical field of metal cutting equipment, and in particular to a profile end face polishing device. Background Technology

[0002] As a key component for the installation and connection of bathroom products, the deburring of the ends of metal rods is an important process to ensure assembly accuracy and safe use.

[0003] In related technologies, manual grinding is the primary method, where operators use handheld grinders to process both ends of the rod one by one. While this method can accommodate various irregularly shaped parts, it results in low production efficiency. Another semi-automated grinding solution uses pneumatic clamps in conjunction with a fixed grinding mechanism. After manual clamping, the equipment is started to complete single-end grinding. Although this reduces labor intensity, it requires changing the clamps when changing shapes, affecting production continuity.

[0004] Regarding the aforementioned technologies, whether manual or semi-automated, the processing mode is "single-strand sequentially, step-by-step at both ends," making it difficult to improve processing efficiency. Summary of the Invention

[0005] In order to improve the profile processing mode of single-section sequential processing and two-stage processing at both ends, and to increase the processing efficiency of profiles, this application provides a profile end face polishing device.

[0006] The profile end face polishing equipment provided in this application adopts the following technical solution: A profile end face polishing device includes polishing mechanisms symmetrically arranged for polishing both ends of the profile, a discharge conveying mechanism for discharging and conveying the profile to the polishing mechanisms, and a drive linear module for driving the polishing mechanisms to move closer to / away from the profile end and along the conveying direction of the profile. The discharge conveying mechanism is vertically arranged above the base of the drive linear module. The discharge conveying mechanism is provided with a plurality of limiting partitions for distributing the profile at intervals, and a clamping mechanism for cooperating with the polishing mechanisms and clamping the profile.

[0007] By adopting the above technical solution, the combination of two symmetrically arranged polishing mechanisms and a vertically positioned material conveying mechanism changes the traditional single-piece sequential processing mode. Multiple limiting baffles spaced at intervals on the material conveying mechanism can simultaneously arrange multiple profiles, achieving batch feeding. The drive linear module drives the polishing mechanism close to both ends of the profiles and along the conveying direction, enabling the equipment to polish both ends of multiple profiles simultaneously. This transforms the sequential, step-by-step operation of single profiles into a multi-profile synchronous, parallel operation, significantly reducing the processing time per piece and increasing the output per unit time, making it more suitable for mass production scenarios.

[0008] Furthermore, the polishing mechanism includes a grinding wheel and a rotating drive seat for driving the grinding wheel to rotate axially. The rotating drive seat is installed on one side of the driving linear module and is perpendicular to the conveying direction of the driving linear module. The rotating drive seat is provided with calipers below, and the length direction of the calipers is parallel to the conveying direction of the material discharge conveying mechanism so as to be used to abut against the end of each profile vertically.

[0009] By adopting the above technical solution, the calipers in the polishing mechanism solve the key technical problem of consistent positioning in batch processing. The calipers' length direction is parallel to the conveying direction of the material feeding mechanism, allowing them to simultaneously and vertically abut against the ends of multiple profiles, ensuring that the end faces of all profiles in the same batch are located on the same reference plane. Using a mechanical unified reference avoids uneven grinding allowance caused by profile length tolerances or deviations in feeding position, enabling the grinding wheel to apply a uniform cutting force to the end of each profile during its travel, ensuring consistency in the surface roughness and flatness of each product during batch processing, and improving the yield rate.

[0010] Furthermore, the material discharge and conveying mechanism includes a positioning base frame and a feeding conveyor belt, with each of the limiting partitions arranged at equal intervals and vertically fixedly connected to the feeding conveyor belt.

[0011] By adopting the above technical solution, the limiting partition is fixed on the closed annular feeding conveyor belt, forming a circular integrated structure for material storage and feeding. This provides a defined feeding position for each profile, solving the problem of isolation and positioning when multiple profiles are fed simultaneously, and preventing collisions or stacking during transport. During feeding, operators only need to sequentially feed the profiles into the processing station at one end of the equipment to complete the subsequent centralized polishing, reducing manual assistance time and lowering the labor intensity of operators.

[0012] Furthermore, the clamping mechanism is located on the side of the feeding conveyor belt close to the polishing mechanism. The clamping mechanism includes a connecting frame for connecting to the positioning base frame, and a horizontal clamping assembly and a vertical clamping assembly disposed on the connecting frame for clamping the profile to be polished.

[0013] By adopting the above technical solution, the connecting frame integrates the horizontal and vertical clamping components on the side near the polishing mechanism, constructing a multi-dimensional composite clamping system. When the polishing mechanism applies axial pressure and rotational friction to the profile end face, the profile is constrained simultaneously from both horizontal and vertical directions, counteracting the vibration and displacement tendencies generated by the cutting force. Compared to single-direction clamping, the composite clamping method significantly improves the profile's posture stability during processing, preventing end face uneven wear or grinding wheel chipping caused by profile swaying, and is particularly adaptable to slender rods or profiles with irregular cross-sections.

[0014] Furthermore, the vertical clamping assembly includes an upper clamping beam and a lower clamping beam arranged symmetrically on the upper and lower sides of the profile, an upper driving member for driving the upper clamping beam, and a lower driving member for driving the lower clamping beam. The connecting frame is provided with an upper mounting beam for mounting the upper driving member and a lower mounting beam for mounting the lower driving member. The connecting frame is provided with a lower mounting plate above the lower mounting beam for mounting the lower clamping beam. The driving end of the lower driving member is fixedly connected to the lower mounting plate.

[0015] By adopting the above technical solution, the symmetrically arranged upper and lower clamping beams work together and are driven independently to achieve adaptive clamping in the thickness direction of the profile. The upper and lower driving components can coordinate their movements according to the actual height of the profile, causing the upper and lower clamping beams to simultaneously move towards the profile until clamping force is applied. This center-type clamping is not only suitable for profile changeover production with different cross-sectional heights, but also ensures that the clamping force line passes through the center of the profile, avoiding profile bending deformation caused by eccentric clamping, ensuring that the profile remains straight during processing, and providing a geometric reference for end-face polishing.

[0016] Furthermore, the horizontal clamping assembly includes a fixed clamping piece, a sliding clamping piece, a sliding mounting plate for mounting the sliding clamping piece, and a sliding drive for driving the sliding mounting plate. A sliding groove is provided along the length direction at the middle position of the lower clamping beam for the sliding mounting plate to be inserted and slid. There are multiple fixed clamping pieces and multiple sliding clamping pieces. Each fixed clamping piece is arranged at equal intervals and vertically fixedly connected to the upper side of the lower clamping beam. The sliding clamping pieces are vertically fixedly connected to the upper side of the sliding mounting plate and are located at adjacent positions of each fixed clamping piece. A clamping gap is left between the fixed clamping piece and the sliding clamping piece for clamping the profile.

[0017] By adopting the above technical solution, the sliding clamping plate moves along the sliding groove under the action of the sliding drive component, forming an adjustable clamping gap with the fixed clamping plate, thus solving the problem of uneven clamping force caused by the accumulation of width tolerances when clamping a batch of profiles simultaneously. When multiple profiles are placed sequentially between the fixed clamping plates and the sliding clamping plates, the linkage movement of the sliding clamping plate can automatically compensate for the width differences of each profile, ensuring that each profile is subjected to a basically uniform lateral clamping force. The flexible clamping mechanism avoids the drawbacks of rigid clamps, such as clamping too tightly in some cases and not clamping firmly in others, and realizes the positioning of multiple specifications of profiles in the same batch.

[0018] Furthermore, the sliding drive component is installed on one side of the lower mounting plate, and an L-shaped connecting strip is fixedly connected between the bottom side of the sliding mounting plate and the driving end of the sliding drive component. A clearance groove is provided on the lower mounting plate for the L-shaped connecting strip to pass through.

[0019] By adopting the above technical solution, the L-shaped connecting strip passes through the clearance slot to connect the sliding drive component and the sliding mounting plate, achieving a compact installation structure and stable transmission. The clearance slot provides clearance space for the L-shaped connecting strip, allowing the power transmission path to be close to the lower clamping beam, reducing the lever arm length and decreasing bending moment and vibration during transmission. The concealed transmission structure avoids interference from exposed connecting rods on the profile conveying, improving the safety of equipment operation.

[0020] Furthermore, the linear drive module includes an X-axis drive module for driving the two polishing mechanisms to move closer to or further away from each other, a Y-axis drive module for driving the two polishing mechanisms to move along or against the conveying direction of the discharge conveying mechanism, a Z-axis drive module for driving the two polishing mechanisms to rise or fall, and a base for mounting each module. The polishing mechanism is mounted on the Z-axis drive module, and the base is provided with a sliding track along the length direction for sliding mounting of the positioning base frame.

[0021] By adopting the above technical solution, the coordinated operation of the three drive modules (X-axis, Y-axis, and Z-axis) enables the polishing mechanism to achieve full-degree-of-freedom adjustment in three-dimensional space. The X-axis drive module ensures that the two polishing mechanisms can be precisely positioned at both ends according to the actual length of the profile; the Y-axis drive module drives the polishing mechanism to sequentially grind and polish the profiles on the conveyor belt; and the Z-axis drive module can adapt to the center-setting requirements of profiles with different cross-sectional heights. The equipment can quickly switch to producing different specifications of profiles without changing mechanical parts, shortening changeover downtime and enhancing the equipment's adaptability to multi-variety batch production.

[0022] Furthermore, a material unloading mechanism for receiving polished profiles is provided downstream of the material unloading conveyor. The material unloading mechanism includes a material unloading conveyor belt and a support column. The material unloading conveyor belt is arranged along the conveying direction of the material loading conveyor belt, and the support column is vertically supported below the material unloading conveyor belt.

[0023] By adopting the above technical solution, an independent unloading conveyor belt is set up downstream of the unloading conveyor mechanism. After the polishing mechanism completes the processing of the profile end face, the unloading conveyor mechanism continues to operate to transport the finished profile to the unloading conveyor belt. The unloading conveyor belt is arranged along the feeding direction, and the material flows clearly and orderly at the fixed unloading end. Operators do not need to wait in the processing area to pick up materials, but can collect finished products in a concentrated manner at fixed intervals, thus optimizing the ergonomic layout.

[0024] Furthermore, the unloading conveyor belt is provided with a limiting post at the end away from the loading conveyor belt to prevent the profile from falling off. The limiting post is arranged vertically and fixedly connected to the side wall of the loading conveyor belt.

[0025] By adopting the above technical solution, the limiting post provides a passive protection device for the end of the feeding conveyor belt, solving the problem of finished profiles falling during the collection process. Because the feeding conveyor belt operates continuously, the profiles have a certain inertia when they reach the end. The limiting post can stop the profiles from continuing to move forward, preventing them from falling directly to the ground and causing impact damage or scattering, thus ensuring the integrity of the finished product collection process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application combines two symmetrically arranged polishing mechanisms with a vertically positioned feeding conveyor, changing the sequential processing mode of single-section, step-by-step processing at both ends. Multiple limiting baffles spaced at intervals on the feeding conveyor can simultaneously arrange multiple profiles, achieving batch feeding. A driving linear module drives the polishing mechanism to synchronously approach both ends of the profile and move along the conveying direction, allowing the polishing mechanism to sequentially polish multiple profiles from both ends in parallel during its movement. This parallel operation mode, with multiple profiles operating synchronously and in parallel at both ends, reduces the average processing time per unit product and increases the output per unit time, making it suitable for high-efficiency processing needs in mass production scenarios. This application solves the quality instability problem caused by profile dimensional tolerances in batch processing through multiple positioning and composite clamping. The calipers in the polishing mechanism can simultaneously and vertically abut against the ends of multiple profiles, ensuring that the end faces of all profiles in the same batch are located on the same reference plane, avoiding uneven grinding allowance due to length tolerances or material layout deviations. The clamping mechanism adopts a composite clamping method in both horizontal and vertical directions. Symmetrical clamping beams with independent drives achieve adaptive centering clamping in the profile thickness direction. The adjustable clamping gap formed by the sliding and fixed clamping plates automatically compensates for width differences among profiles. This multi-dimensional precise positioning and flexible clamping mechanism ensures a high degree of consistency in the surface roughness and flatness of each product's end face during batch processing, improving the yield rate. This application enhances the equipment's adaptability and automation level to various profile specifications through the synergy of a three-dimensional, fully adjustable linear drive module and a modular conveyor system. Three drive modules along the X, Y, and Z axes enable the polishing mechanism to precisely position itself according to the actual length and cross-sectional height of the profile, allowing for rapid switching between different product specifications without replacing mechanical parts, significantly reducing changeover downtime. The integrated feeding structure of the feeding conveyor belt, the independent downstream unloading conveyor belt, and the end-position limit protection device construct a complete automated production process from batch feeding, automatic clamping, synchronous polishing to centralized unloading.

[0034] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-6 The present application will be further described in detail with reference to the embodiments.

[0035] This application discloses a profile end face polishing device. (Refer to...) Figure 1 The profile end-face polishing equipment includes a discharge conveying mechanism 1, a clamping mechanism 2, a polishing mechanism 3, a drive linear module 4, and a feeding mechanism 5. In this embodiment, the polishing mechanism 3 consists of two sets arranged symmetrically, and the two sets of polishing mechanisms 3 can be used to polish both ends of the profile respectively. The discharge conveying mechanism 1 can discharge multiple profiles of the same batch and convey them to the polishing mechanism 3.

[0036] After the material conveying mechanism 1 delivers the profile to its position, the clamping mechanism 2 clamps and positions both ends of the profile in both horizontal and vertical directions. Then, the driving linear module 4 drives the polishing mechanism 3 to approach / move away from the ends of the profile and move along the conveying direction of the profile, thereby sequentially polishing the ends of multiple profiles. The unloading mechanism 5 collects the polished profiles.

[0037] Reference Figure 1 and Figure 2 The linear drive module 4 includes a base 41, an X-axis drive module 42, a Y-axis drive module 43, and a Z-axis drive module 44. The base 41 is for mounting each drive module. The base 41 has a sliding track 411 on its upper side along the length direction for sliding mounting of the Y-axis drive module 43 and the material conveying mechanism 1. The Z-axis drive module 44 is mounted on the Y-axis drive module 43, and the polishing mechanism 3 is mounted on the Z-axis drive module 44.

[0038] The X-axis drive module 42 drives the two polishing mechanisms 3 to move closer to or further apart, thereby polishing the end face of the profile located between the two polishing mechanisms 3. The Y-axis drive module 43 drives the two polishing mechanisms 3 to move along or against the conveying direction of the material discharge conveyor 1, so that the polishing mechanisms 3 can polish the end of the profile sequentially during the movement, and then drive the polishing mechanisms 3 to return along the original path after polishing is completed. The Z-axis drive module 44 drives the two polishing mechanisms 3 to rise or fall, so that the polishing mechanisms 3 can adapt to the center setting requirements of profiles with different cross-sectional heights.

[0039] The polishing mechanism 3 includes a grinding wheel 31 and a rotary drive seat 32. The rotary drive seat 32 is mounted on the side wall of the Z-axis drive module 44 and is used to drive the grinding wheel 31 to rotate axially. The rotary drive seat 32 is perpendicular to the conveying direction of the drive linear module 4, thereby driving the grinding wheel 31 to complete the polishing action.

[0040] In this embodiment, calipers 33 are provided below the rotating drive seats 32 of both polishing mechanisms 3. The length direction of the calipers 33 is parallel to the conveying direction of the material feeding mechanism 1, so that the two calipers 33 can be perpendicularly abutted against both ends of each profile. The calipers 33 can ensure that the end faces of all profiles in the same batch are located on the same reference plane. Using a mechanical unified reference avoids the problem of uneven grinding allowance caused by profile length tolerance or material feeding position deviation, so that the grinding wheel 31 can apply a uniform cutting force to the end of each profile during the process, ensuring the consistency of the surface roughness and flatness of each product during batch processing.

[0041] Reference Figure 1 and Figure 3The material discharge conveying mechanism 1 is vertically arranged above the base 41 of the drive linear module 4. The material discharge conveying mechanism 1 includes a positioning base frame 11 and a feeding conveyor belt 12. The material discharge conveying mechanism 1 is slidably mounted on the sliding rail 411 via the positioning base frame 11, and the positioning base frame 11 and the sliding rail 411 are fixedly connected. Multiple limiting partitions 121 are arranged at equal intervals and vertically fixedly connected on the feeding conveyor belt 12. Each limiting partition 121 is used to arrange the profiles at intervals, providing a definite feeding position for each profile, solving the problem of isolation and positioning when multiple profiles are fed at the same time, and preventing the profiles from colliding or stacking with each other during the conveying process.

[0042] Reference Figure 3 and Figure 4 The unloading mechanism 5 is located downstream of the discharge conveyor mechanism 1 and is used to receive the polished profiles. The unloading mechanism 5 includes an unloading conveyor belt 51 and a supporting column 52. The unloading conveyor belt 51 is arranged along the conveying direction of the loading conveyor belt 12, and the supporting column 52 is vertically supported below the unloading conveyor belt 51. At the end of the unloading conveyor belt 51 away from the loading conveyor belt 12, a limiting post 53 is provided to prevent the profiles from falling. The limiting post 53 is vertically arranged and fixedly connected to the side wall of the loading conveyor belt 12.

[0043] Reference Figure 5 and Figure 6 The clamping mechanism 2 is located on the side of the feeding conveyor belt 12 near the polishing mechanism 3, and is used to cooperate with the polishing mechanism 3 to clamp the profile. The clamping mechanism 2 includes a connecting frame 21, a horizontal clamping assembly 22 and a vertical clamping assembly 23. The connecting frame 21 is fixedly connected to the positioning base frame 11. The horizontal clamping assembly 22 and the vertical clamping assembly 23 are located on the connecting frame 21 and are used to clamp the profile to be polished.

[0044] The vertical clamping assembly 23 includes an upper clamping beam 231, a lower clamping beam 232, an upper drive member 233, a lower drive member 234, an upper mounting beam 235, a lower mounting beam 236, and a lower mounting plate 237. The upper clamping beam 231 and lower clamping beam 232 are symmetrically arranged vertically and used to clamp the upper and lower sides of the profile. The upper mounting beam 235 is horizontally arranged and fixedly connected to the upper part of the connecting frame 21. The upper drive member 233 is mounted on the upper mounting beam 235 and used to drive the upper clamping beam 231. The lower mounting beam 236 is horizontally arranged and fixedly connected to the lower part of the connecting frame 21. The drive cylinder of the lower drive member 234 is mounted on the lower mounting beam 236 to drive the lower clamping beam 232. The lower mounting plate 237 is horizontally arranged and fixedly connected to the connecting frame 21 and located above the lower mounting beam 236. The lower clamping beam 232 is fixedly connected to the top side of the lower mounting plate 237, and the driving end of the lower driving component 234 is fixedly connected to the side of the lower mounting plate 237.

[0045] The horizontal clamping assembly 22 includes a fixed clamping piece 221, a sliding clamping piece 222, a sliding mounting plate 223, and a sliding drive component 224. The sliding mounting plate 223 is used to mount the sliding clamping piece 222. The lower clamping beam 232 has a sliding groove 2321 along its length at the middle position for the sliding mounting plate 223 to engage and slide. In this embodiment, there are multiple fixed clamping pieces 221 and multiple sliding clamping pieces 222. Each fixed clamping piece 221 is equidistantly spaced and vertically fixed to the upper side of the lower clamping beam 232. The sliding clamping pieces 222 are vertically fixed to the upper side of the sliding mounting plate 223 and are located one-to-one with each adjacent position of the fixed clamping piece 221. A clamping gap 2221 for clamping the profile is provided between the fixed clamping piece 221 and the sliding clamping piece 222. The drive cylinder of the sliding drive component 224 is fixedly connected to one side of the lower mounting plate 237 to drive the sliding mounting plate 223. An L-shaped connecting strip 225 is fixedly connected between the bottom side of the sliding mounting plate 223 and the drive end of the sliding drive component 224. A clearance slot 2371 is provided on the lower mounting plate 237 for the L-shaped connecting strip 225 to pass through.

[0046] The implementation principle of the profile end face polishing equipment in this application embodiment is as follows: When the equipment is working, the operator first places multiple profiles to be processed sequentially on the feeding conveyor belt 12. The limiting partitions 121 fixed at equal intervals on the surface of the conveyor belt separate and arrange the profiles, ensuring that each profile is independently positioned and does not interfere with each other, and moves forward step by step with the conveyor belt. When the profile is conveyed to the processing station near the polishing mechanism 3, the X-axis drive module 42 in the linear drive module first drives the caliper 33 to abut against both ends of the profile, and performs preliminary position adjustment on both ends of the multiple profiles. After the caliper 33 returns along the original path, the clamping mechanism 2 adopts a horizontal and vertical two-way compound clamping method for the profile. In the horizontal clamping assembly 22, the sliding drive component 224 drives the sliding mounting plate 223 to move along the sliding groove 2321 through the L-shaped connecting strip 225, so that multiple sliding clamping pieces 222 move synchronously toward the fixed clamping piece 221, and laterally clamp the multiple profiles arranged in the horizontal direction. Because the sliding clamping plate 222 can be adjusted in a linked manner, it can automatically compensate for the width tolerance of each profile, ensuring that each profile is subjected to a uniform and stable clamping force. In the vertical clamping assembly 23, the upper clamping beam 231 and the lower clamping beam 232 move towards the profile synchronously under the action of the upper driving member 233 and the lower driving member 234, and clamp the profile from the top and bottom directions to ensure that the profile maintains a straight posture.

[0047] After the profile is clamped, the linear drive module 4 performs motion control. The X-axis drive module 42 drives the two symmetrically arranged polishing mechanisms 3 to move closer to each other according to the actual length of the profile, so that the grinding wheels 31 move to predetermined positions at both ends of the profile. The Z-axis drive module 44 adjusts the vertical height of the polishing mechanism 3 according to the profile cross-sectional height, so that the center of the grinding wheel 31 is aligned with the center of the profile end face. Subsequently, the Y-axis drive module 43 drives the polishing mechanism 3 to move at a constant speed along the conveying direction of the discharge conveyor 1, while rotating the drive seat 32 to drive the grinding wheel 31 to rotate at high speed, continuously polishing the profile end face.

[0048] After the polishing stroke is completed, the Y-axis drive module 43 drives the polishing mechanism 3 back along the original path, the clamping mechanism 2 is released, and the feeding conveyor belt 12 continues to move forward, sending the polished profile to the downstream unloading conveyor belt 51, while simultaneously sending the next set of profiles to be processed into the processing station. The limiting post 53 at the end of the unloading conveyor belt 51 prevents the profile from falling accidentally and facilitates the operators to collect the finished products.
