Description

Technical Field

[0001] This utility model relates to the field of sanding disc processing technology, specifically to a slanted sanding disc forming device. Background Technology

[0002] A slanted abrasive disc is an abrasive disc with slanted surfaces, primarily used for grinding workpieces. The abrasive disc is made by bonding abrasive sheets cut to a specific shape to a metal or non-metal substrate using an adhesive. It features good self-sharpening properties, high efficiency, and good heat dissipation.

[0003] During the production of beveled sanding discs, the outer edges of the initially assembled discs may be uneven. While this unevenness doesn't significantly affect the sanding effect, it negatively impacts the final appearance, lowering the product's grade and hindering future sales. The common practice to address this is to manually lift the beveled sanding disc and bring its edge into contact with the flywheel at the output of the sanding motor for trimming. This process requires manually switching the angle and orientation of the disc multiple times, resulting in relatively low efficiency and posing safety hazards due to the close-range manual operation. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a beveled sanding disc forming device to solve the problems mentioned in the background art, which are that the existing beveled sanding disc forming and trimming operation requires manual switching of the angle and orientation of the sanding disc multiple times during the grinding process, resulting in relatively low efficiency, and manual close-range operation also poses certain safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sloped sanding disc forming device, comprising a base, a support frame fixed on one side of the upper end of the base, a positioning seat and a rotary drive assembly for driving the positioning seat to rotate horizontally are movably installed at the bottom of one straight section of the support frame, a guide rod and a telescopic electric cylinder for driving the guide rod to move horizontally are slidably installed on the lower part of the positioning seat, an inverted U-shaped frame is fixedly installed on one end of the guide rod, a grinding machine and a drive assembly for driving the grinding machine to rotate vertically are rotatably installed on the inner side and lower end of the U-shaped frame, the bottom output end of the grinding machine is also provided with a milling cutter, a telescopic electric cylinder is vertically arranged on one side of the upper end of the base, and a sanding disc positioning assembly for horizontally positioning the sloped sanding disc is provided at the top output end of the telescopic electric cylinder.

[0007] After the sanding disc positioning assembly installs and fixes the inclined sanding disc, the rotating positioning seat and the inclined sanding disc move perpendicularly and coaxially.

[0008] As a preferred embodiment of the inclined sand sheet forming device of this utility model, one end of the horizontal section of the support frame has a mounting hole;

[0009] The rotary drive assembly includes a shaft disk fixed at the center of the top of the positioning seat and mounted inside the mounting hole via a bearing, and a servo motor mounted on the top of the support frame and whose output end is coaxially connected to the shaft disk.

[0010] As a preferred embodiment of the inclined sand disc forming device of this utility model, the lower end of the positioning seat is horizontally fixed with a positioning bushing that is slidably sleeved on the outside of the guide rod, and the guide rod has a connecting block fixedly connected to the piston rod end of the telescopic electric cylinder at the opposite end of the inverted U-shaped frame.

[0011] As a preferred embodiment of the inclined sanding disc forming device of this utility model, the grinding machine has rotating shafts fixed on both sides and rotatably mounted on both sides of the inverted U-shaped frame via bearings. A second servo motor is also fixed on the outside of the U-shaped frame, and the output shaft end of the second servo motor is coaxially connected to the rotating shaft.

[0012] As a preferred embodiment of the inclined sanding disc forming device of this utility model, the sanding disc positioning component includes an electromagnetic chuck horizontally fixed to the top output shaft end of the telescopic electric cylinder, an air expansion shaft vertically fixed to the top axis of the electromagnetic chuck, a pressure plate movably sleeved on the outside of the air expansion shaft, and a handle fixed to the top of the metal pressure plate.

[0013] As a preferred embodiment of the inclined sand sheet forming device of this utility model, the upper side of the support frame is further provided with the main control unit of the forming device, namely the PLC controller H.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This inclined sanding disc forming device horizontally positions the initially formed sanding disc using a sanding disc positioning component. Then, the PLC controller H controls the telescopic electric cylinder 2 to adjust the horizontal height of the sanding disc so that the edge of the sanding disc matches the milling cutter. The servo motor 2 is controlled to adjust the grinding angle of the grinding machine and the milling cutter. The telescopic electric cylinder 1, in conjunction with the guide rod, adjusts the distance between the milling cutter and the edge of the sanding disc. Simultaneously, the servo motor 1 is started. In this way, the started grinding machine rotates at a uniform speed along the radial direction of the sanding disc, and the highly rotating milling cutter quickly grinds and trims the edge of the sanding disc. The entire operation only requires fixing the sanding disc with the positioning component and then activating the PLC controller H. Compared with the existing manual trimming operation, the processing efficiency and grinding effect are effectively improved, while avoiding the safety hazards of manual close-range operation.

Detailed Implementation

[0020] 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.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figure 1-Figure 4 The diagram shown is a complete structural schematic of the inclined sand sheet forming device of this utility model. Please refer to [link / reference]. Figure 1-Figure 4 This embodiment of a sloped sand sheet forming device includes a base 100, a support frame 200 fixed to one side of the upper end of the base 100, a positioning seat 300 and a rotary drive assembly 400 for driving the positioning seat 300 to rotate horizontally are movably installed at the bottom of one straight end of the support frame 200, a guide rod 310 and a telescopic electric cylinder 320 for driving the guide rod 310 to move horizontally are slidably installed on the lower part of the positioning seat 300, and an inverted U-shaped frame 500 is fixedly installed at one end of the guide rod 310, with the inner side of the U-shaped frame 500 and The lower end is longitudinally rotatably mounted with a grinding machine 600 and a drive assembly for driving the grinding machine 600 to rotate longitudinally. The bottom output end of the grinding machine 600 also has a milling cutter 610. A telescopic electric cylinder 700 is vertically arranged on one side of the upper end of the base 100. The top output end of the telescopic electric cylinder 700 is equipped with a sanding disc positioning assembly 800 for horizontal positioning of the inclined sanding disc. After the sanding disc positioning assembly 800 is installed and fixed on the inclined sanding disc, the rotating positioning seat 300 and the inclined sanding disc move perpendicularly and coaxially.

[0024] The support frame 200 has a mounting hole 210 at one end of its horizontal section. The rotary drive assembly 400 includes a shaft disk 410 fixed at the center of the top of the positioning seat 300 and mounted inside the mounting hole 210 via bearings, and a servo motor 420 mounted on the top of the support frame 200 with its output end coaxially connected to the shaft disk 410. It can be understood that the servo motor 420 drives the shaft disk 410 to rotate horizontally, thereby driving the positioning seat 300 and the grinding machine 600 to rotate synchronously, causing the grinding machine 600 to rotate and move radially along the sanding disc, thus achieving rapid edge trimming. A positioning sleeve 330 is horizontally fixed at the lower end of the positioning seat 300 and slidably sleeved on the outside of the guide rod 310. The guide rod 310 has a connecting block 340 fixedly connected to the piston rod end of the telescopic electric cylinder 320 at the opposite end of the inverted U-shaped frame 500. The grinding machine 600 has rotating shafts 510 fixed on both sides and rotatably mounted on both sides of the inverted U-shaped frame 500 via bearings. A second servo motor 520 is also fixed to the outside of the U-shaped frame 500, and the output shaft of the second servo motor 520 is coaxially connected to the rotating shafts 510. It is understandable that, since different models and specifications of inclined sanding discs have different thicknesses and corresponding grinding angles, the grinding angle of the grinding machine 600 and the milling cutter 610 can be tilted and adjusted by the cooperation of the U-shaped frame 500, the rotating shafts 510, and the second servo motor 520, which is more precise and convenient than manual operation based on experience. Specifically, in this embodiment, the initially formed sanding disc is horizontally positioned using the sanding disc positioning component 800. Then, the PLC controller H controls the telescopic electric cylinder 700 to adjust the horizontal height of the sanding disc so that the edge of the sanding disc matches the milling cutter 610. The servo motor 520 is controlled to adjust the grinding angle of the grinding machine 600 and the milling cutter 610. The telescopic electric cylinder 320 is controlled and, with the cooperation of the guide rod 310, adjusts the distance between the milling cutter 610 and the edge of the sanding disc. The servo motor 420 is started simultaneously. In this way, the started grinding machine 600 rotates at a constant speed along the radial direction of the sanding disc, and the highly rotating milling cutter 610 quickly grinds and trims the edge of the sanding disc. The entire operation only requires fixing the sanding disc with the positioning component 800 and then activating the PLC controller H. Compared with the existing manual trimming operation, the processing efficiency and grinding effect are effectively improved, while avoiding the safety hazards of manual close-range operation.

[0025] It is important to note that before use, staff should pre-set each drive and adjustment unit through the PLC controller H, so that the next round of sanding and polishing can be carried out quickly.

[0026] Preferably, the sanding disc positioning assembly 800 further includes an electromagnetic chuck 810 horizontally fixed to the top output shaft of the telescopic electric cylinder 700, an air shaft 820 vertically fixed to the top axis of the electromagnetic chuck 810, a pressure plate 830 movably sleeved on the outside of the air shaft 820, and a handle 840 fixed to the top of the metal pressure plate 830. It can be understood that the air shaft 820 allows for quick centering and positioning of the sanding disc horizontally placed on the electromagnetic chuck 810. Simultaneously, to prevent the sanding disc from swaying during grinding, the metal pressure plate 830 can be directly pressed onto the electromagnetic chuck 810. Electromagnetic attraction causes the metal pressure plate 830 to firmly press and fix the sanding disc, simplifying operation.

[0027] Preferably, a PLC controller H, the central control unit of the molding device, is further provided on one side of the upper end of the support frame 200. It can be understood that, with the cooperation of the PLC controller H, operators can perform integrated control and activation settings of the device, further optimizing processing efficiency.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
