Description

Technical Field

[0001] The utility model belongs to the field of hardware processing, in particular to an edge grinding device for processing aluminum alloy doors and windows. Background Art

[0002] In the existing process of grinding the inner and outer corners of aluminum alloy doors and windows, a manual handheld electric grinder is usually used to grind the inner corners of the inner groove of the aluminum alloy doors and windows and the outer corners of the outer frame. However, when grinding the inner corners of the inner groove of the aluminum alloy doors and windows, due to the dim visual environment in the inner groove, it is difficult for workers to determine whether it is polished smoothly during the grinding process, so that the workers need to grind it repeatedly. This grinding method not only increases the labor cost.

[0003] Chinese utility model patent CN219310962U discloses an aluminum alloy door and window corner grinding device, which controls a screw transmission adjustment bracket installed on one side of a movable support plate to drive a grinding roller to perform longitudinal reciprocating motion, thereby causing a grinding outer disc to drive a grinding block and a grinding roller to be clamped in an embedded groove of an aluminum alloy door and window frame to grind the inner corners of the aluminum alloy door and window frame. Through the operation of motor two and motor one, the device can repeatedly and evenly control the grinding outer disc, the grinding block and the grinding roller to grind the inner corners of the aluminum alloy door and window frame, thereby reducing the labor cost of the device and improving the uniformity and integrity of the grinding.

[0004] When grinding aluminum alloy doors and windows, the inner surface needs to be grinded in all directions. Since the aluminum alloy doors and windows need to be fixed on a workbench during grinding, the aluminum alloy doors and windows usually need to be turned over on the side opposite to the workbench before grinding. Therefore, the aluminum alloy doors and windows need to be clamped twice to a certain extent, which prolongs the grinding time. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] In order to solve the problems of the above-mentioned background technology, the utility model adopts the following technical solutions.

[0007] A grinding device for processing aluminum alloy doors and windows, including a grinding platform, rollers are provided at both ends of the grinding platform, tracks are sleeved between the rollers, grinding particles are attached to the outer surface of the tracks, a bracket and a gantry are mounted on the grinding platform, cantilever structures are symmetrically provided on the bracket, and the ends of the cantilever structures are rotatably connected to side grinding rollers, a fixed rod is provided in the center of the upper end of the gantry, a cylinder is installed on the fixed rod, the output end of the cylinder passes through the fixed rod and is connected to a grinding plate, a pair of cross bars are symmetrically provided on the sides of the gantry, and a double-axis cylinder is assembled on the lower surface of one of the cross bars.

[0008] Preferably, a support plate is provided between the rollers at both ends of the grinding platform, the thickness of the support plate is equal to the diameter of the roller, and when the crawler track is sleeved on the roller, the surface of the support plate contacts the inner surface of the crawler track.

[0009] Preferably, a driver is installed on the outside of one end of the grinding platform, and the driver is connected to one of the ends of the rollers. The other end of the roller connected to the driver and the other end of the roller are both equipped with bearing seats.

[0010] Preferably, auxiliary plates are mounted at both ends of the grinding platform and outside the roller, the auxiliary plates are provided with a plurality of mounting grooves at equal intervals, and a plurality of supporting wheels are rotatably connected in the mounting grooves, and the surfaces of the supporting wheels are flush with the upper surface of the track.

[0011] Preferably, the cantilever structure includes a fixed arm fixedly connected to the inner side of the bracket, and a telescopic arm is movably inserted at the front end of the fixed arm, a first U-shaped plate is provided at the end of the telescopic arm, and the side grinding roller is connected to the first U-shaped plate by a rotating shaft.

[0012] Preferably, the tool on the upper surface of the fixed arm is provided with a plurality of through holes, and the inner threads of the through holes are connected with abutment bolts, and when the abutment bolts are rotated clockwise, the bottoms thereof abut against the upper surface of the telescopic arm.

[0013] Preferably, a spring shock absorber is centrally disposed on the lower surface of the upper end of the bracket, a second U-shaped plate is disposed at the lower end of the spring shock absorber, and a main grinding roller is mounted in the second U-shaped plate via a rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The grinding device in the utility model can grind the surface of the aluminum alloy without turning over the aluminum alloy. When the aluminum alloy is placed on the grinding device, it does not need to be moved a second time, thereby reducing the preparation time required for grinding to a certain extent and improving the grinding efficiency.

[0016] (2) Generally speaking, since the aluminum alloy needs to be placed on a grinding platform, the side in contact with the grinding platform needs to be turned over before it can be exposed for grinding. However, in the present invention, a symmetrical double-axis cylinder is provided, and the aluminum alloy is fixed by the double-axis cylinder. The surface of the crawler used to drive the aluminum alloy to move is provided with grinding particles. When the crawler rotates and the aluminum alloy is clamped by the double-axis cylinder, the crawler can grind the side of the aluminum alloy in contact with it, while the side and upper surface of the aluminum alloy are directly grinded by other grinding components, so that the grinding device can grind the aluminum alloy at one time without moving the aluminum alloy multiple times.

[0017] (3) In the present invention, the grinding of the upper surface of the aluminum alloy is mainly carried out by the cooperation of a grinding plate and a grinding roller. In the grinding process, the grinding plate belongs to sliding friction, which can provide greater friction, help to quickly remove materials and improve grinding efficiency. The grinding roller belongs to rolling friction. Due to the small contact area and dispersed friction, the heat generated is relatively small, which helps to protect the material and reduce thermal damage. The rolling friction causes relatively little wear on the abrasive tool, which can extend the service life of the abrasive tool. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Ginseng Figure 1 and Figure 2 The present embodiment is an edge grinding device for processing aluminum alloy doors and windows. The edge grinding device in the present embodiment comprises a grinding platform 100. Both ends of the grinding platform 100 are provided with rollers 102a. A crawler 102c is sleeved between the rollers 102a. In the present embodiment, the crawler 102c is used to transport the aluminum alloy doors and windows for horizontal movement. At the same time, a bracket 104 and a gantry 105 are mounted on the grinding platform 100. When the aluminum alloy doors and windows pass through the bracket 104 and the gantry 105 in sequence, a cantilever structure is symmetrically provided on the bracket 104, and the cantilever structure is The end of the arm structure is rotatably connected to a side grinding roller 104b-1a, a fixed rod 105b is provided in the center of the upper end of the gantry 105, a cylinder 105b-1 is installed on the fixed rod 105b, the output end of the cylinder 105b-1 passes through the fixed rod 105b and is connected to a grinding plate 105b-1a, and the aluminum alloy doors and windows pass through the grinding roller 104b-1a and the grinding plate 105b-1a through the track 102c, and the upper surface and side of the aluminum alloy doors and windows are polished by the grinding roller 104b-1a and the grinding plate 105b-1a.

[0029] See also Figure 1 and Figure 5Since the aluminum alloy needs to be placed on the grinding platform 100, the side in contact with the grinding platform 100 needs to be turned over before it can be exposed for grinding. This process will prolong the preparation work for grinding. Therefore, in this embodiment, grinding particles are attached to the outer surface of the track 102c, and a pair of cross pieces 105a are symmetrically provided on the side of the gantry 105, and the lower surface of one of the cross pieces 105a is equipped with a double-axis cylinder 105a-1, and the aluminum alloy is fixed by the double-axis cylinder 105a-1. The surface of the track 102c used to drive the aluminum alloy to move is provided with grinding particles. When the track 102c rotates and the aluminum alloy is clamped by the double-axis cylinder 105a-1, the track 102c can grind the side of the aluminum alloy in contact with it through the grinding particles, and when the aluminum alloy is not clamped by the double-axis cylinder 105a-1, the grinding particles can increase the friction between the aluminum alloy and the track 102c, thereby improving the conveying efficiency.

[0030] See also Figure 2 When the aluminum alloy is placed on the crawler 102c, the crawler 102c will fall due to gravity. At this time, the aluminum alloy cannot be completely in contact with the crawler 102c, which leads to low efficiency during grinding. Therefore, in this embodiment, a support plate 101 is provided between the rollers 102a at both ends of the grinding platform 100. The thickness of the support plate 101 is equal to the diameter of the roller 102a. When the crawler 102c is sleeved on the roller 102a, the surface of the support plate 101 contacts the inner surface of the crawler 102c, and the support plate 101 provides support for the crawler 102c to prevent the crawler 102c from being crushed. The belt 102c is partially concave due to the gravity of the aluminum alloy; further, in order to realize the operation of the track 102c, a driver 102 is installed on the outer side of one end of the grinding platform 100 in this embodiment, and the driver 102 is connected to the end of one of the rollers 102a. The other end of the roller 102a connected to the driver 102 and the end of the other roller 102a are both equipped with bearing seats 102b. The driver 102 drives one of the rollers 102a to rotate as the output end, and the other roller 102a serves as the driven end to support the track 102c.

[0031] See 2 and Figure 3Considering the length and weight of the aluminum alloy, its gravity will inevitably increase when grinding a longer aluminum alloy. Simply relying on the movement of the track 102c cannot drive the aluminum alloy to move. Therefore, in this embodiment, auxiliary plates 103 are mounted on both ends of the grinding platform 100 and outside the roller 102a. The auxiliary plates 103 are equidistantly provided with a plurality of mounting grooves, and a plurality of supporting wheels 103a are rotatably connected in the mounting grooves. The supporting wheels 103a have a surface flush with the upper surface of the track 102c. The two ends of the aluminum alloy are lifted by the supporting wheels 103a, thereby dispersing the gravity of the aluminum alloy. When the track 102c moves, it drives the aluminum alloy to move synchronously. The aluminum alloy rubs against the supporting wheels 103a to make the supporting wheels 103a roll. During the rolling process, the supporting wheels 103a transmit the rolling force to the aluminum alloy, thereby assisting the track 102c in transporting the aluminum alloy.

[0032] See also Figure 4 Considering the different widths of aluminum alloys for doors and windows, a pair of side grinding rollers 104b-1a at a fixed distance cannot meet the needs of grinding different profiles. Therefore, the cantilever structure in this embodiment includes a fixed arm 104a fixedly connected to the inner side of the bracket 104, and a telescopic arm 104b is movably inserted at the front end of the fixed arm 104a, and a first U-shaped plate 104b-1 is provided at the end of the telescopic arm 104b. The side grinding roller 104b-1a is connected to the first U-shaped plate 104b-1 by a rotating shaft. In this embodiment, the telescopic arm 104b can be telescoped in the fixed arm 104a, thereby adjusting the distance between the pair of first U-shaped plates 104b-1. In order to achieve adjustment of the spacing of the side grinding rollers 104b-1a, and to ensure that after the telescopic arm 104b is adjusted, the resistance force when the side grinding rollers 104b-1a contact the aluminum alloy will not react on the telescopic arm 104b, causing the telescopic arm 104b to move accidentally, the tool on the upper surface of the fixed arm 104a in this embodiment is provided with a plurality of through holes, and the inner threads of the through holes are connected with resistance bolts 104a-1, and when the resistance bolts 104a-1 are rotated clockwise, the bottom thereof abuts against the upper surface of the telescopic arm 104b, and the telescopic arm 104b is fixed by abutting against the upper surface of the telescopic arm 104b through one or more resistance bolts 104a-1.

[0033] Furthermore, in order to improve the grinding efficiency, a spring shock absorber is provided in the center of the lower surface of the upper end of the bracket 104 in this embodiment, and a second U-shaped plate 104c is provided at the lower end of the spring shock absorber. A main grinding roller 104c-1 is assembled in the second U-shaped plate 104c through a rotating shaft, and grinding is performed by the cooperation of the grinding plate 105b-1a and the main grinding roller 104c-1. In the grinding process, the grinding plate 105b-1a belongs to sliding friction, and sliding friction can provide greater friction, which helps to quickly remove materials and improve grinding efficiency. The main grinding roller 104c-1 belongs to rolling friction. Due to the small contact area and dispersed friction, the heat generated is relatively small, which helps to protect the material and reduce thermal damage. The rolling friction causes relatively little wear on the grinding tool, which can extend the service life of the grinding tool.
