Description

Technical Field

[0001] This utility model relates to the field of sheet metal grinding, specifically a deburring mechanism using a sanding belt. Background Technology

[0002] The belt sander deburring mechanism removes burrs from sheet metal parts by using a roller-driven belt and friction between the belt and the surface of the sheet metal. During operation, the driven roller may deviate, so a correction mechanism is often designed to correct the belt's deviation. Existing correction mechanisms use a cylinder to drive the driven roller support to rotate dynamically. A PLC control system then controls the cylinder's output to extend or retract, causing the driven roller support to swing in the opposite direction of the deflection, achieving dynamic correction. Static correction is achieved by adjusting the cylinder's position. However, the existing structure directly drives the cylinder seat via a lead screw and slider. Because stress is concentrated on the lead screw, the entire correction mechanism vibrates during dynamic correction, causing wear between the nut connected to the slider and the lead screw.

[0003] For example, Chinese patent CN 213615894 U discloses a belt correction device for a wide-band sander, including a fixed base. A cylinder seat is mounted inside the fixed base via a sliding adjustment mechanism, and a cylinder is mounted inside the cylinder seat. Fixed plates are mounted on the left and right ends of the cylinder via adjusting components. By loosening the fixing bolts and adjusting the position of the slider, the position of the cylinder can be adjusted. Simultaneously, by controlling the extension and retraction of the cylinder's output end, the position of the fixed plates is adjusted. The fixed plates are fixed to the top tension roller support beam, causing a change in the angle between the tension roller and the thickness roller, thereby achieving the correction function. The aforementioned wide belt sander correction device can only achieve correction by moving the fixed plate driven by the cylinder, thereby causing the top tension roller to deflect. This type of correction is called dynamic correction. The entire dynamic correction method is to directly adjust the movement of the cylinder seat by the slider driven by the lead screw. There is no limit on the side of the slider. The weight of the entire cylinder seat and cylinder is applied to the slider, which makes the lead screw bear a large load. During the operation of the sander, the vibration of the cylinder will accelerate the wear of the lead screw nut.

[0004] Therefore, it is necessary to provide a deburring mechanism for abrasive belts. Utility Model Content

[0005] This utility model provides a deburring mechanism for sanding belts, which effectively solves the problem of easy wear of the slider and lead screw of the bearing cylinder of the sander's correction mechanism.

[0006] The technical solution adopted in this utility model is: A belt deburring mechanism includes a support, a drive roller mounted on the support, a first cylinder mounted vertically on the support, a cantilever mounted at the output end of the first cylinder, a driven roller mounted on the cantilever, a belt drivingly connected to the drive roller and the driven roller, and a drive component mounted below the support to drive the drive roller to rotate. The support also includes a correction assembly, which includes a base mounted on the support and having a first groove, a sliding support block slidably mounted on the groove, a second cylinder mounted on the sliding support block, a lead screw mounted on the base, and a slanted slider threaded onto the lead screw. The lower end face of the sliding support block has a slanted groove, and the slanted slider is slidably connected to the slanted groove. The lead screw drives the slanted slider to move, causing the slanted slider to drive the sliding support block to slide along the first groove.

[0007] Furthermore, the sliding support block includes a first block and two cylinder support seats bolted on the first block. The inclined slide groove is located on the lower end face of the first block. The first block is slidably connected to the first slide groove. The first cylinder is located on the cylinder support block.

[0008] Furthermore, the two cylinder support seats are symmetrically arranged on the upper end face of the first block. The cylinder support seat includes a base plate bolted to the first block and a side plate arranged on the side of the base plate. The side plate is bolted to the cylinder body side of the second cylinder. The two cylinder support seats are bolted to both sides of the second cylinder respectively.

[0009] Furthermore, the correction assembly also includes a knob that is coaxially fixedly connected to one end of the lead screw protruding from the base.

[0010] Furthermore, the base includes a seat body mounted on a bracket and limiting blocks symmetrically arranged on both sides of the seat body. Each limiting block includes a baffle bolted to the upper end face of the seat body and a horizontal plate mounted on the upper end of the baffle. The upper end face of the seat body, the baffles of the two limiting blocks, and the horizontal plate form the first sliding groove. The upper end face of the sliding support block abuts against the lower end face of the horizontal plate, the lower end face of the sliding support block abuts against the upper end face of the seat body, and the two sides of the sliding support block abut against the two baffles respectively.

[0011] Furthermore, the cantilever includes a support arm rotatably mounted at the output end of the first cylinder, a connecting frame mounted at the lower end of one side of the support arm, bearing seats mounted on the upper surfaces of both sides of the support arm, and two ball bearings respectively mounted in the bearing seats. The driven roller is connected at both ends to the inner rings of the two ball bearings respectively, and the output end of the second cylinder is connected to the connecting frame.

[0012] Furthermore, the driving component includes a motor, a driving pulley mounted on the motor shaft, a driven pulley coaxially fixed on the driving roller, and a synchronous belt, wherein the driving pulley and the driven pulley are connected to the synchronous belt for transmission.

[0013] The beneficial effects of the utility model are as follows: The correction component can not only achieve static and dynamic correction, but also utilize the sliding support block and the base through the sliding groove. The base supports the sliding support block so that the weight of the cylinder is not transmitted to the inclined slider, thereby reducing the vibration of the inclined slider and the lead screw during dynamic correction and reducing the wear of the lead screw during dynamic correction.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the embodiment of this application provides a belt deburring mechanism, the structure of which includes a support 1, a drive roller 2 mounted on the support 1, a first cylinder 3 vertically mounted on the support 1, a cantilever 4 mounted at the output end of the first cylinder 3, a driven roller 5 mounted on the cantilever 4, a sanding belt (not shown in the figure) that is drively connected to the drive roller 2 and the driven roller 5, and a drive member 6 mounted below the support 1 to drive the drive roller 2 to rotate. The support 1 also has a correction assembly 7. Figure 2 and Figure 3As shown, the correction assembly 7 includes a base 71 mounted on the bracket 1 and provided with a first slide groove 710, a sliding support block 72 slidably mounted on the slide groove, a second cylinder 73 mounted on the sliding support block 72, a lead screw 74 mounted on the base 71, and a slanted slider 75 threaded onto the lead screw 74. The lower end face of the sliding support block 72 is provided with a slanted slide groove 720, and the slanted slider 75 is slidably connected to the slanted slide groove 720. The lead screw 74 drives the slanted slider 75 to move, causing the slanted slider 75 to drive the sliding support block 72 to slide along the first slide groove 710.

[0020] It should be noted that the lead screw 74 is mounted on the base 71 via a lead screw 74 seat. After the deburring mechanism of this application is installed on the frame, a displacement sensor installed on the frame senses the position of the driven roller 5 and controls the second cylinder 73 of the correction assembly 7 through the PLC control system. After the displacement sensor senses the offset of the driven roller 5, the PLC control system receives the offset and controls the second cylinder 73 to perform high-frequency, small-amplitude extension and retraction at any point within its stroke range to track and counteract the belt deviation. For example, if the displacement sensor detects that the driven roller 5 causes the belt to deviate 1mm to the left, the PLC control system controls the output end of the second cylinder 73 to extend 1mm to the right. After the sanding belt is assembled, cylinder 3 lifts the cantilever 4, causing the driven roller 5 to tension the sanding belt. In actual use, the drive unit 6 drives the active roller 2 to rotate, which, in conjunction with the driven roller 5, drives the sanding belt transmission. If belt deviation occurs during transmission, dynamic correction is achieved through the correction component 7. The principle of the correction component 7 is as follows: before the drive unit 6 is driven after assembly, static correction is performed first. By rotating the lead screw 74, the inclined slider 75 slides along the axial direction of the lead screw 74. The friction between the inclined slider 75 and the inclined groove 720 drives the sliding support block 72 to slide along the first groove 710, thereby enabling the sliding support block 72 to drive the second cylinder 73 to move synchronously. The second cylinder 73 then drives the cantilever 4 and the driven roller 5 to deflect around the output end of the first cylinder 3, achieving initial static correction. When the drive unit 6 is operating the sanding belt transmission, the lead screw 74, the inclined slider 75, the sliding support plate, and the second cylinder 73 are all fixed. When the driven roller 5 deviates due to vibration during operation, the PLC control system controls the output end of the second cylinder 73 to extend or retract in the opposite direction within the stroke range to deflect the cantilever 4 in the opposite direction, thereby achieving dynamic correction.

[0021] In the above design, the correction component 7 can not only achieve static and dynamic correction, but also utilize the sliding support block 72 and the base 71 through the sliding groove to support the sliding support block 72, so that the weight of the cylinder is not transmitted to the inclined slider 75, thereby reducing the vibration of the inclined slider 75 and the lead screw 74 during dynamic correction and reducing the wear of the lead screw 74 during dynamic correction.

[0022] Specifically: such as Figure 2 and Figure 3 As shown, the sliding support block 72 includes a first block 721 and two cylinder support seats 722 bolted on the first block 721. The inclined slide groove 720 is disposed on the lower end face of the first block 721. The first block 721 is slidably connected to the first slide groove 710. The first cylinder 3 is disposed on the cylinder support block.

[0023] In actual use, the No. 1 cylinder 3 is fixed to the cylinder support block by bolts. The rotation of the lead screw 74 causes the inclined slider 75 to drive the No. 1 block 721 to slide along the inclined slide groove 720, thereby realizing the synchronous movement of the No. 1 block 721, the cylinder support seat 722, and the No. 2 cylinder 73. The No. 2 cylinder 73 drives the cantilever 4 and the driven roller 5 to deflect.

[0024] In the above design, the structural design and specific implementation of the sliding support block 72 can achieve a fixed connection to the second cylinder 73.

[0025] Specifically: such as Figure 2 and Figure 3 As shown, two cylinder support seats 722 are symmetrically arranged on the upper surface of the first block 721. Each cylinder support seat 722 includes a base plate 7221 bolted to the first block 721 and a side plate 7222 disposed on the side of the base plate 7221. The side plate 7222 is bolted to the cylinder body side of the second cylinder 73. The two cylinder support seats 722 are bolted to both sides of the second cylinder 73 respectively.

[0026] During actual assembly, bolts are used to fix the cylinder 73 to both sides of the second cylinder by passing through the two cylinder support seats 722 respectively.

[0027] In the above design, the base plate 7221 is fixed to the upper end face of the first block 721 by bolts to ensure the fixation of the cylinder support seat 722 to the first block 721. The second cylinder 73 is fixed to the side plate 7222 by bolts to ensure the fixation of the second cylinder 73 to the cylinder support seat 722.

[0028] Specifically: such as Figure 2 and Figure 3 As shown, the correction assembly 7 also includes a knob 76 that is coaxially fixedly connected to one end of the lead screw 74 protruding from the base 71.

[0029] In actual use, the lead screw 74 is rotated by turning the knob 76.

[0030] In the above design, the knob 76 is set in the Forbidden City to facilitate the rotation of the lead screw 74, thereby facilitating the static correction function of the correction component 7.

[0031] Specifically: such as Figure 2 and Figure 3As shown, the base 71 includes a base body 711 mounted on the bracket 1 and limiting blocks 712 symmetrically arranged on both sides of the base body 711. Each limiting block 712 includes a baffle 7121 bolted to the upper end face of the base body 711 and a horizontal plate 7122 mounted on the upper end of the baffle 7121. The upper end face of the base body 711 and the baffle 7121 and horizontal plate 7122 of the two limiting blocks 712 form the first sliding groove 710. The upper end face of the sliding support block 72 abuts against the lower end face of the horizontal plate 7122, and the lower end face of the sliding support block 72 abuts against the upper end face of the base body 711. The two sides of the sliding support block 72 abut against the two baffles 7121 respectively.

[0032] In actual use, the sliding support block 72 is limited on both sides by two baffles 7121 during the sliding process, and the upper end is limited by a horizontal plate 7122.

[0033] In the above design, the structural design and specific implementation of the base 71 can effectively achieve cooperation with the sliding support block 72.

[0034] Specifically: such as Figure 1 As shown, the cantilever 4 includes a support arm 41 located at the output end of the first cylinder 3, a connecting frame 42 located at the lower end of one side of the support arm 41, bearing seats 43 located on the upper surfaces of both sides of the support arm 41, and two ball bearings 44 respectively located in the bearing seats 43. The driven roller 5 is connected to the inner rings of the two ball bearings 44 at both ends, and the output end of the second cylinder 73 is connected to the connecting frame 42.

[0035] When the actual correction is performed, the correction component 7 drives the connecting frame 42 to rotate, which in turn drives the support arm 41, bearing seat 43 and ball bearing 44 to rotate synchronously, thereby driving the driven roller 5 to rotate to achieve correction.

[0036] In the above design, the structural design and specific implementation of the cantilever 4 can effectively realize the assembly of the driven roller 5 and its cooperation with the correction component 7.

[0037] Specifically: such as Figure 1 As shown, the driving component 6 includes a motor 61, a driving pulley mounted on the rotating shaft of the motor 61, a driven pulley 63 coaxially fixed on the driving roller 2, and a synchronous belt 62. The driving pulley, the driven pulley 63, and the synchronous belt 62 are connected in a transmission manner.

[0038] In actual use, the motor 61 drives the active pulley to rotate, and with the cooperation of the synchronous belt 62, the driven pulley 63 drives the active roller 2 to rotate, and with the cooperation of the driven roller 5, it drives the sand belt transmission.

[0039] In the above design, the structural design and specific implementation of the drive component 6 can effectively drive the sanding belt.

[0040] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
