Description

Technical Field

[0001] The utility model relates to the technical field of positioning of double-end surface grinders, in particular to a method for quickly positioning a double-end surface grinder.

[0002] Double-end surface grinding machine with mechanism. Background Art

[0003] A double-disc grinder is a machine tool specifically designed for efficiently grinding two parallel workpiece surfaces. It can grind both the top and bottom surfaces simultaneously in a single clamping operation, significantly improving machining efficiency and precision. This machine uses two grinding heads to grind both ends of the workpiece simultaneously. The workpiece is typically mounted on a rotating platform, while the grinding heads are fixed above and below the machine. The grinding heads perform the grinding operation while the workpiece rotates.

[0004] However, in practice, the material channel positioning mechanism of double-disc grinders presents several issues. The positioning mechanism's slow response speed results in excessively long positioning times during the grinding process, which reduces production efficiency. On high-speed production lines, this lack of speed can directly impact production schedules. The slow positioning mechanism can also cause slight workpiece displacement during positioning, affecting the surface accuracy of the finished workpiece, ultimately compromising workpiece quality and potentially increasing scrap rates.

[0005] Furthermore, the existing double-disc grinder's material channel positioning mechanism is not user-friendly and requires complex assembly and disassembly. When adjusting or replacing the positioning mechanism, operators must disassemble each mechanism piece by piece, which not only increases operation time but also potentially damages the equipment. This inconvenience results in a lengthy adjustment or replacement process, which significantly increases production cycle time and reduces efficiency. Utility Model Content

[0006] The main purpose of the utility model is to provide a double-end surface grinder with a rapid positioning mechanism, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A double-end face grinder with a rapid positioning mechanism includes a machine base, a material channel, a drive device, a grinder assembly, a control box, a lifting device, and a docking conveyor. The drive devices are located on both sides of the upper end of the machine base, and the grinder assembly is located in the middle section of the upper end of the machine base. Two drive devices are symmetrically arranged on both sides of the grinder assembly. A lifting device and a control box are provided between the two sets of the machine bases. The lifting device and the grinder assembly are connected through the material channel and the docking conveyor.

[0009] A side frame is provided at the material channel of the machine base, a mounting frame is connected in the clamping cavity between the two side frames, and a hydraulic cylinder is provided at the inner end of the mounting frame, and the extension direction of the hydraulic cylinder is consistent with the feeding and discharging direction of the material channel;

[0010] The telescopic end of the hydraulic cylinder is connected with a connecting piece, and a rotating frame is connected to the connecting piece. The lower end of the rotating frame is connected with a material positioning block through a connecting frame. The material positioning block is driven by the hydraulic cylinder to position the material on the material channel.

[0011] As a further preferred solution of the present invention, the mounting frame is fixed on the side frame by bolts, the hydraulic cylinder is fixedly welded to the mounting frame, and the telescopic end of the hydraulic cylinder is threadedly connected to the connecting piece;

[0012] As a further preferred solution of the present invention, the connecting piece and the rotating frame are fixed by a connecting rod, and the rotating frame is designed in an "L" shape;

[0013] As a further preferred solution of the present invention, the connecting frame and the rotating frame are perpendicular to each other, and a wedge block is provided at the connection between the connecting frame and the rotating frame. The rotating frame is placed in the cavity between the two wedge blocks, and the rotating frame and the connecting frame are fixed by bolts;

[0014] As a further preferred solution of the present invention, the cross sections of the connecting frame and the material positioning block are designed in a "丿" shape, and the connecting frame and the material positioning block are integrally designed;

[0015] As a further preferred solution of the present invention, an anti-slip rubber strip is adhesively connected to the lower end surface of the material positioning block. After being driven by the hydraulic cylinder, the lower end surface of the material positioning block is designed to be parallel to the material channel, which is convenient for positioning the material in the material channel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, the quick positioning mechanism can quickly adjust the position of the material positioning block through the telescopic movement of the hydraulic cylinder, thereby shortening the positioning time of the material in the material channel. This quick response mechanism reduces the preparation time of the material before grinding, makes the entire grinding process smoother, and thus improves the working efficiency of the entire grinding machine and the material handling speed. Through the precise cooperation of the rotating frame and the connecting frame, the material positioning block can accurately move to the designated position and ensure that its lower end surface is parallel to the material channel. This precise positioning mechanism ensures the stability and consistency of the material during the grinding process, thereby improving the positioning accuracy.

[0018] The efficient operation of the quick positioning mechanism reduces material preparation time before grinding, thereby shortening the entire processing cycle. Rapid positioning and adjustment reduce waiting and calibration time, allowing grinding work to be started and completed more quickly, thereby reducing processing time. The precise control of the quick positioning mechanism and the use of anti-slip rubber strips ensure material stability and accuracy during the grinding process. This not only prevents material slippage during grinding but also ensures a uniform grinding process, thereby improving the surface quality of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 4 As shown, a double-end surface grinder with a rapid positioning mechanism includes a machine base 1, a material channel 2, a drive device 3, a grinding assembly 4, a control box 5, a lifting device 6, and a docking conveyor 7. The drive devices 3 are located on both sides of the upper end of the machine base 1, and the grinding assembly 4 is located in the upper middle section of the machine base 1. The two drive devices 3 are symmetrically arranged on either side of the grinding assembly 4. The lifting device 6 and the control box 5 are installed between the two sets of machine bases 1. The lifting device 6 and the grinding assembly 4 are connected via the material channel 2 and the docking conveyor 7.

[0026] At the material channel 2 of the machine base 1, there is a side frame 8, and an installation frame 9 is connected in the cavity between the two side frames 8. The inner end of the installation frame 9 is provided with a hydraulic cylinder 10, and the extension direction of the hydraulic cylinder 10 is consistent with the incoming and outgoing material direction of the material channel 2. The telescopic end of the hydraulic cylinder 10 is connected with a connecting piece 11, and the connecting piece 11 is connected with a rotating frame 12. The lower end of the rotating frame 12 is connected with a material positioning block 14 through a connecting frame 13, and the hydraulic cylinder 10 is used to drive the rotating frame 12 to achieve rapid positioning of the material on the material channel 2.

[0027] The installation frame 9 is fixed on the side frame 8 by bolts, the hydraulic cylinder 10 is fixedly welded with the installation frame 9, and the telescopic end of the hydraulic cylinder 10 is threadedly connected with the connecting piece 11. The connecting piece 11 and the rotating frame 12 are fixed by a connecting rod, and the rotating frame 12 is designed in an "L" shape. The connecting frame 13 and the rotating frame 12 are perpendicular to each other, and a wedge block is provided at the connection between the connecting frame 13 and the rotating frame 12. The rotating frame 12 is placed in the cavity between the two wedge blocks, and the rotating frame 12 and the connecting frame 13 are fixed by bolts.

[0028] The cross-section of the connecting frame 13 and the material positioning block 14 is designed in a "丿" shape, and the connecting frame 13 and the material positioning block 14 are integrally designed. The lower end surface of the material positioning block 14 is adhesively connected with an anti-slip rubber strip. After being driven by the hydraulic cylinder 10, the lower end surface of the material positioning block 14 is designed to be parallel to the material channel 2, which is convenient for positioning the material in the material channel 2.

[0029] This design of the double-sided grinding machine enables the positioning of the material in the material channel 2 to be more rapid and accurate, improving the working efficiency of the grinding machine and the material processing speed. Through the telescopic movement of the hydraulic cylinder 10, the position of the material positioning block 14 can be quickly adjusted to ensure the stability and accuracy of the material during the grinding process. In addition, the use of the anti-slip rubber strip further enhances the reliability of the material positioning, prevents the material from slipping during the grinding process, and ensures the grinding quality.

The hydraulic cylinder 10 drives the connecting piece 11 and the rotating frame 12 to rotate through telescopic movement. The rotating frame 12 drives the connecting frame 13 and the material positioning block 14 for positioning. The lower end surface of the material positioning block 14 is parallel to the material channel 2 to ensure stable positioning of the material. The driving device 3 drives the grinding machine component 4 to start the grinding work. After grinding is completed, the material is sent to the next process or output through the lifting device 6 and the docking conveyor 7.

[0031] Material positioning process: The material is placed on the material channel 2. The hydraulic cylinder 10 extends and retracts, pushing the connector 11 and the rotating frame 12. The rotating frame 12 rotates, driving the material positioning block 14 through the connecting frame 13. The material positioning block 14 moves to the designated position, with the lower end surface parallel to the material channel 2. The anti-slip rubber strip of the material positioning block 14 contacts the material, ensuring its stability. After the material is positioned, the grinding machine assembly 4 begins grinding.
