Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a deburring device for grinding the edges and corners of a filing cabinet. Background Technique

[0002] The main structure of the filing cabinet is composed of metal square tubes and metal plates by welding or riveting. Usually, aluminum alloy plates or iron plates are cut into appropriate sizes and welded on the metal frame. Before assembly, the outer edges and corners are usually punched with a punching machine to make the edges and corners smooth. After electrostatic powder spraying the frame and each component, they are assembled together. Before assembling the filing cabinet, it is necessary to grind the edges exposed on the outside or in the storage room to prevent cutting people or cutting the file bag when taking out the file bag.

[0003] Since most of the edges of the metal plates are hidden during assembly, it is not necessary to grind the edges of all the metal plates. The edges of the metal plates that need to be ground are usually ground with a handheld sander or a angle grinder. Both of these machines are designed for flat grinding. When grinding the edges, the worker needs to adjust the grinding angle, and a single line needs to be ground multiple times to make the edge not sharp. Long-term manual grinding work is likely to make the worker fatigued, further affecting the work efficiency and grinding quality.

[0004] During the use stage of the filing cabinet, due to external bumps or corrosion, the sprayed plastic protective layer on the surface falls off, and the edges of the metal parts of the cabinet body are sharp or corroded due to scratches, all of which require re-grinding and subsequent protection treatment. The angle grinder is still inconvenient for novice users. There is a need for a high-efficiency, accurate and convenient deburring device for grinding the edges and corners of a filing cabinet, which can be easily used by file managers and can quickly grind the sharp edges smoothly. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the above difficulties and provide a deburring device for grinding the edges and corners of a filing cabinet.

[0006] To solve the above technical problem, the technical solution provided by the utility model is: a deburring device for grinding the edges and corners of a filing cabinet, including a housing, a handle is provided on the top of the housing, a grinding mechanism is provided inside the housing, the grinding mechanism includes a sand belt, and a rotation driving mechanism for rotating the sand belt is provided inside the housing;

[0007] The grinding mechanism also includes a connecting frame, an inner shaft and an outer shaft. A slide is slidably arranged in the shell. Two connecting frames are symmetrically hinged at the bottom of the slide. Two ends of the connecting frame are hinged to the inner shaft and the outer shaft respectively. The hinge axis of the connecting frame and the inner shaft coincides with the hinge axis of the connecting frame and the slide. The sanding belt is coated on the outside of the two inner shafts and the two outer shafts. The rotating drive mechanism is transmission-connected to one of the inner shafts. A swinging drive mechanism is arranged in the shell for driving the slide to move back and forth laterally in the shell. The rotating drive mechanism and the swinging drive mechanism are arranged in a power box on the rear side of the shell.

[0008] As an improvement: an internal support mechanism is provided between the slide and the connecting frame, the internal support mechanism includes two internal support rods and a lifting platform, one end of the internal support rod is hinged to the connecting frame, the other ends of the two internal support rods are hinged to the lifting platform, a positioning rod is provided on the top of the lifting platform, an extension plate is provided at the bottom of the driving slide, the extension plate is provided with a through hole that slides with the positioning rod, and a spring is provided between the extension plate and the lifting platform.

[0009] As an improvement: the driving mechanism includes motor 1 and gear 2, the output end of motor 1 is provided with gear 1 meshing with gear 2, gear 2 is rotatably arranged in the power box, one end of gear 2 is provided with a spline shaft, and one of the inner shaft ends is provided with a spline groove matching the spline shaft.

[0010] As an improvement: the swing drive mechanism includes motor 2, a turntable and a rocker arm, the output end of motor 2 is provided with bevel gear 1, one side of the turntable is coaxially connected with bevel gear 2 meshing with bevel gear 1, an eccentric shaft is provided at the eccentric position of the other side of the turntable, and the two ends of the rocker arm are respectively hinged to the eccentric shaft and the slide.

[0011] As an improvement: support rods are symmetrically arranged on the connecting frame, and abutment tubes are rotatably arranged between the support rods on the same side.

[0012] As an improvement: a walking mechanism is arranged outside the shell, and the walking mechanism comprises an outer bracket hingedly arranged on both sides of the shell, a transverse plate is arranged on the outer bracket, and a plurality of rollers are rotatably arranged on the transverse plate.

[0013] As an improvement: the front end of the shell is threadedly connected with a fastening bolt, and one end of the outer bracket is hinged to the smooth rod body of the fastening bolt.

[0014] As an improvement: guard plates abutting against the connecting frame are provided on both sides of the bottom of the shell.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the utility model drives the abrasive belt to rotate by setting a rotary drive mechanism, and uses a swing drive mechanism to make the grinding mechanism move back and forth horizontally. When grinding the edges and corners of the filing cabinet, burrs can be quickly removed and the corners can be rounded. Compared with the traditional manual grinding method, the grinding efficiency and convenience of use are greatly improved. Specifically:

[0016] 1. The connecting frame, inner shaft, and outer shaft in the grinding mechanism cooperate with each other, enabling the abrasive belt to be adaptively adjusted according to the shape of the ground corner. For example, when grinding the right-angle edge line of a filing cabinet or the corner of a rectangular column, the abrasive belt can closely adhere to the corner, and together with the pressure tube, press the abrasive belt against the side of the corner, ensuring the uniformity of grinding, ensuring that each corner can obtain a good grinding effect, effectively avoiding uneven grinding, and improving the stability of product quality;

[0017] 2. The equipment is equipped with a walking mechanism. Just place the device on the corner to be ground, adjust the outer bracket so that the rollers contact the side of the corner, and tighten the fixing bolts to fix the walking mechanism to start the grinding work. The whole operation process is simple and easy to understand, without the need for professional skill training, reducing the technical requirements for operators. At the same time, the automated grinding method greatly reduces the labor intensity of workers, reduces manual fatigue, and improves the comfort and sustainability of work;

[0018] 3. The inner support mechanism set between the sliding frame and the connecting frame, through the coordinated action of the inner support rod, lifting platform, and spring, can push the lifting platform to move up and down when the connecting frame rotates, enabling the connecting frame to rotate synchronously and with the same rotation angle, ensuring that the two pressure tubes can press the abrasive belt against the side of the corner synchronously, further optimizing the grinding effect. In addition, the equipment has a compact structure and reasonable layout of each component. It is not only applicable to the grinding of the right-angle edge line of a filing cabinet, but also can grind the narrow edges of the columns or plates of a filing cabinet by adjusting the walking mechanism, with strong applicability and can meet the needs of various corner grinding in the production process of filing cabinets.

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a filing cabinet corner grinding and deburring device includes a shell 1, a handle 12 is provided on the top of the shell 1, a grinding mechanism 3 is provided in the shell 1, the grinding mechanism 3 includes a sanding belt 31, a rotation drive mechanism 5 is provided in the shell 1 for rotating the sanding belt 31, a swing drive mechanism 6 is provided in the shell 1 for driving a slide 4 to move back and forth laterally in the shell 1, and the rotation drive mechanism 5 and the swing drive mechanism 6 are arranged in a power box 11 on the rear side of the shell 1.

[0030] Combined with Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, the grinding mechanism 3 also includes a connecting frame 32, an inner shaft 33 and an outer shaft 34, a slide 4 is slidably provided in the shell 1, two connecting frames 32 are symmetrically hinged at the bottom of the slide 4, two ends of the connecting frame 32 are respectively hinged to the inner shaft 33 and the outer shaft 34, the hinge axis of the connecting frame 32 and the inner shaft 33 coincides with the hinge axis of the connecting frame 32 and the slide 4, the sanding belt 31 is coated on the outside of the two inner shafts 33 and the two outer shafts 34, the driving mechanism 5 is transmission-connected to one of the inner shafts 33, support rods 321 are symmetrically provided on the connecting frame 32, and abutment tubes 35 are rotatably provided between the support rods 321 on the same side.

[0031] Working principle of the grinding mechanism 3: The rotation drive mechanism 5 drives one of the inner shafts 33 to rotate, thereby driving the abrasive belt 31 to rotate outside the inner shaft 33 and the outer shaft 34. The connecting frame 32 can rotate. As shown in Figure 5 In the figure, the distances between the two inner shafts 33 and between the inner shaft 33 and the outer shaft 34 on the same side are fixed, while the distance between the two outer shafts 34 can be changed, so that the shape of the abrasive belt 31 between the two outer shafts 34 can be changed. That is, when fitting to the grinding corner, by pressing the abrasive belt 31, the connecting frame 32 rotates until the abutting pipe 35 presses the abrasive belt 31 against the two side surfaces of the grinding corner. During the rotation of the abrasive belt 31, the corner is ground. Similarly, when grinding a rectangular column, the front of the rectangular column abuts the abrasive belt 31 against the two abutting pipes 35, and the outer shaft 34 is close to the two side surfaces of the rectangular column, so as to grind the two corners in front of the rectangular column at the same time.

[0032] Combined with the attached Figure 5 and the attached Figure 8 As shown in the figure, an inner support mechanism 7 is provided between the carriage 4 and the connecting frame 32. The inner support mechanism 7 includes two inner support rods 71 and a lifting platform 72. One end of the inner support rod 71 is hinged to the connecting frame 32, and the other ends of the two inner support rods 71 are both hinged to the lifting platform 72. A positioning rod 73 is provided at the top of the lifting platform 72. An extension plate 41 is provided at the bottom of the driving carriage 4. A through hole slidably matched with the positioning rod 73 is provided on the extension plate 41. A spring 74 is provided between the extension plate 41 and the lifting platform 72. On both sides of the bottom of the housing 1, there are guard plates 13 abutting against the connecting frame 32.

[0033] Working principle of the inner support mechanism 7: When the connecting frame 32 rotates, the lifting platform 72 is pushed up and down by the inner support rod 71, and the lifting platform 72 is pushed down by the spring 74, so as to reset the connecting frame 32. Since the two inner support rods 71 are of equal length and the hinge axes of the inner support rods 71 and the lifting platform 72 coincide, the connecting frame 32 rotates synchronously and by the same rotation angle, so that the two abutting pipes 35 can press the abrasive belt 31 against the side surfaces of the corner synchronously.

[0034] Combined with the attached Figure 1 and the attached Figure 6 As shown in the figure, the rotation drive mechanism 5 includes a motor one 51 and a gear two 53. A gear one 52 meshing with the gear two 53 is provided at the output end of the motor one 51. The gear two 53 is rotatably arranged in the power box 11. A spline shaft 54 is provided at one end of the gear two 53. A spline groove 331 cooperating with the spline shaft 54 is provided at the end of one of the inner shafts 33.

[0035] Working principle of the rotation drive mechanism 5: The motor one 51 drives the gear one 52 to rotate. Through the meshing transmission between the gear one 52 and the gear two 53, the spline shaft 54 is driven to rotate. Through the cooperation between the spline shaft 54 and the spline groove 331, the inner shaft 33 is driven to rotate, so that the abrasive belt 31 rotates.

[0036] Combined with the attached Figure 1and the attached Figure 7 As shown, the swing drive mechanism 6 includes a second motor 61, a turntable 64, and a swing rod 66. A first bevel gear 62 is provided at the output end of the second motor 61. A second bevel gear 63 meshing with the first bevel gear 62 is coaxially connected to one side of the turntable 64. An eccentric shaft 65 is provided at an eccentric position on the other side of the turntable 64. Both ends of the swing rod 66 are respectively hinged to the eccentric shaft 65 and the carriage 4.

[0037] Working principle of the swing drive mechanism 6: The second motor 61 drives the first bevel gear 62 to rotate. Through the meshing transmission between the first bevel gear 62 and the second bevel gear 63, the turntable 64 is driven to rotate. The eccentric shaft 65 rotates around the axis of the turntable 64, and the carriage 4 is driven by the swing rod 66 to reciprocate horizontally in the housing 1.

[0038] Combined with the attached Figure 1 As shown, a traveling mechanism 2 is provided outside the housing 1. The traveling mechanism 2 includes outer brackets 21 hinged to both sides of the housing 1. A cross plate 22 is provided on the outer brackets 21. A plurality of rollers 23 are rotatably provided on the cross plate 22. The front end of the housing 1 is threadedly connected with a fastening bolt 24. One end of the outer bracket 21 is hinged to the smooth rod body of the fastening bolt 24.

[0039] Working principle of the traveling mechanism 2: Place the device on the corner to be polished. Then adjust the outer bracket 21 so that the rollers 23 contact the side of the corner. Tighten the fastening bolt 24 to fix the traveling mechanism 2. During polishing, the traveling mechanism 2 travels on the polished part. The traveling mechanism 2 can also ensure the fixed relative position between the polishing mechanism 3 and the polished corner during movement. For example, when polishing multiple right-angled edges, the traveling mechanism 2 can always maintain a fixed position. When polishing a rectangular column, adjust the angle of the outer bracket 21.

[0040] When the present utility model is specifically implemented, place the device on the right-angled edge of the filing cabinet that needs to be polished. Then adjust and fix the traveling mechanism 2. The polishing mechanism 3 makes the abrasive belt 31 press on the corner through displacement, so as to grind off the burrs on the corner and grind it into a rounded corner. Drive the abrasive belt 31 to rotate through the rotation drive mechanism 5, and make the polishing mechanism 3 reciprocate horizontally through the swing drive mechanism 6, thereby improving the polishing efficiency. After the right-angled edge of the filing cabinet is polished, adjust the traveling mechanism 2 to polish the narrow side of the column or plate body of the filing cabinet.

[0041] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited to this. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they should all fall within the protection scope of the present utility model.
