Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a machine tool body 1 and a dressing table 2; both the machine tool body 1 and the dressing table 2 are mounted on the ground using guide rails, and the dressing table 2 is located on the right side of the machine tool body 1.

[0028] It also includes:

[0029] The buffer rod 3, there are several buffer rods 3, and the bottom ends of the several buffer rods 3 are inserted at equal intervals on the surface of the machine tool body 1 to facilitate the transmission of the stress.

[0030] Buffer plates 4, there are several buffer plates 4, each fixed to the bottom end of the buffer rod 3, and the buffer plates 4 are movably arranged in the buffer groove 5 inside the machine tool body 1. The ring wall of the buffer plate 4 is engaged with the inner wall of the buffer groove 5 to transfer the stress to the gas in the buffer groove 5 through the buffer plate 4, so as to avoid the workpiece being overloaded and damaged. The top surface of the machine tool body 1 is provided with several sealing rings 18, and the buffer rod 3 is movably inserted into the sealing rings 18 to prevent the processed debris from falling into the buffer groove 5.

[0031] An air inflator 6 is installed inside the machine tool body 1 and is connected to several buffer tanks 5 to facilitate control of the air pressure intensity in the buffer tanks 5.

[0032] The control pipe 7 is located on the front side of the machine tool body 1. The end of the control pipe 7 is connected to the air charging pipe 6. The control pipe 7 is equipped with an air valve 8. The control pipe 7 is connected to an external air pump. The air valve 8 is used to adjust the switch of the control pipe 7 to avoid air leakage.

[0033] The fixing plate 9 is set on the top surface of the machine tool body 1, and the fixing plate 9 is connected to the top of several buffer rods 3, so as to facilitate placing the workpiece on the fixing plate 9;

[0034] The top surface of the machine tool body 1 is provided with a protective component 10, which includes:

[0035] The protective frame 11 consists of two frames, with the vertical bars of the two protective frames 11 symmetrically inserted into the machine tool body 1, and the fixing plate 9 located between the two protective frames 11. The pressure sensor 12 is installed on the horizontal bar of the protective frame 11 and is electrically connected to the dressing seat 2. The height of the pressure sensor 12 is controlled by the protective frame 11, which makes it easy to adjust the pressure sensor 12 to the same height as the processing position of the workpiece.

[0036] Two electric push rods 13 are symmetrically fixed on the machine tool body 1, and the output end of the electric push rod 13 is connected to the protective frame 11. The electric push rod 13 is connected to an external power source to facilitate the control of the lifting and lowering of the protective frame 11.

[0037] A contact frame 14 is movably mounted on the outer shell of the dressing seat 2. The crossbar of the contact frame 14 is screwed onto the output end of the dressing seat 2 via a rotor. The crossbar of the contact frame 14 is in contact with the pressure sensor 12, so that the stress applied by the output shaft of the dressing seat 2 is applied to the pressure sensor 12 through the contact frame 14. When the applied stress exceeds the stress level of the workpiece, the output shaft of the dressing seat 2 is stopped. Support rods 15 are symmetrically fixed on the contact frame 14. The two ends of the support rods 15 are connected to the vertical rod and the crossbar of the contact frame 14 to improve the strength of the crossbar of the contact frame 14 and prevent the crossbar of the contact frame 14 from bending. A protective pad 16 is provided on the bottom surface of the crossbar of the contact frame 14, and the protective pad 16 is in contact with the pressure sensor 12 to protect the pressure sensor 12 to a certain extent.

[0038] When using this utility model, the operator first uses an external air pump to input gas into the buffer tank 5 through the inflation pipe 6. Then, the operator controls the air pressure intensity in the buffer tank 5 according to the reading on the air pressure detector 17 until the pressure reaches a suitable value. Then, the operator seals the control pipe 7 through the air valve 8 to prevent air leakage. After that, the workpiece is installed on the fixed plate 9. The height of the crossbar of the protective frame 11 is adjusted by the electric push rod 13, and the pressure sensor 12 is adjusted to a suitable height. The output shaft of the dressing seat 2 is started, so that the output shaft drives the processing tool to contact the workpiece. The output shaft drives the contact frame 14 to descend synchronously, so that the crossbar of the contact frame 14 abuts against the pressure sensor 12. When the value on the pressure sensor 12 exceeds the specified range, the descent of the output shaft of the dressing seat 2 is stopped to avoid damaging the workpiece. When the tool processes the workpiece, the stress applied by the tool to the workpiece is transmitted to the buffer tank 5 through the buffer rod 3. The air pressure is used to buffer and reduce the stress on the workpiece, thus avoiding damage to the workpiece.

[0039] Compared with the prior art, the beneficial effects of this utility model are:

[0040] By using the control tube 7 and the air inlet tube 6 in conjunction, the gas pressure in the buffer groove 5 is adjusted, thereby buffering the stress on the workpiece on the fixed plate 9 and preventing the workpiece from being damaged by the overload stress of the tool on the dressing seat 2.

[0041] The protection component 10 is set up so that the contact frame 14 moves synchronously with the output shaft of the correction seat, so that the contact frame 14 abuts against the pressure sensor 12 to detect the downward stress of the output shaft of the correction seat 2. The pressure sensor 12 is used to control the start of the output shaft to avoid overload of the output shaft pressure in the correction seat 2.

[0042] A support rod 15 is provided to increase the strength of the contact frame 14 and prevent the crossbar of the contact frame 14 from bending under stress.

[0043] A sealing ring 18 is installed to block the gap between the buffer rod 3 and the machine tool body 1, preventing the processing debris from falling into the buffer groove 5.

[0044] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
