Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a tool clamping mechanism for a numerically controlled lathe. Background Art

[0002] The clamping mechanism usually refers to the device used to clamp and fix the workpiece. Its main function is to complete the loading, unloading and positioning of the workpiece. According to the scope of use of the machine tool clamping mechanism, the clamping mechanism can be divided into general clamping devices, special clamping devices and adjustable clamping devices.

[0003] The fixing effect of the existing machine tool clamping mechanism is unstable, and the tool is prone to shaking or shifting during work, which reduces the processing accuracy of the product and requires the operator to constantly adjust the position of the tool, causing the lathe to stop for too long and reducing the processing efficiency. At the same time, the shaking of the tool during work will also cause uneven force, thereby aggravating the wear of the tool and reducing the service life of the tool. Utility Model Content

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a tool clamping mechanism for a CNC lathe, comprising a clamping mechanism 1, a cooling mechanism 2 is fixedly installed on the top of the clamping mechanism 1;

[0026] The clamping mechanism 1 includes a shell 101, an acoustic emission monitor 102 is arranged on the top of the shell 101, two baffles 103 are fixedly installed on the inner surface wall of the shell 101, the tops of the two baffles 103 are in contact with a card block 104, and the outer walls of the two card blocks 104 are in contact with the inner surface wall of the shell 101, a tool 105 is fixedly installed between the outer walls of the two card blocks 104, a circular hole 106 is opened on the outer wall of the shell 101, and two mounting holes 107 are opened on the outer wall of the shell 101, and the inner walls of the two mounting holes 107 are movably inserted with an extrusion plate 108, and the inner walls of the two extrusion plates 108 are provided with anti-skid pads 109, and the two anti-skid pads 109 are The outer walls are in contact with the outer walls of the tool 105, the outer walls of the two extrusion plates 108 are fixedly installed with mounting plates 110, the inner walls of the two mounting plates 110 are fixedly installed with a group of springs 111, and the outer walls of the two groups of springs 111 are fixedly connected to the outer wall of the shell 101, the tops of the two mounting plates 110 are fixedly installed with ear blocks 112, the outer walls of the two ear blocks 112 are provided with threaded holes 113, the inner walls of the two threaded holes 113 are threadedly connected with a bidirectional threaded rod 114, and the inner wall of the circular hole 106 is movably inserted with the outer wall of the bidirectional threaded rod 114, and an adjusting wheel 115 is fixedly installed on one side of the outer wall of the bidirectional threaded rod 114.

[0027] The effect achieved by the entire embodiment 1 is that the operator first inserts the tool 105 into the shell 101, and then rotates the tool 105 and the two baffles 103 on the surface so that the two baffles 103 are inserted between the shell 101 and the two baffles 103. Then the operator can rotate the adjusting wheel 115 to drive the two ear blocks 112 to move through the bidirectional threaded rod 114. The two ear blocks 112 can squeeze the two sets of springs 111 through the two mounting plates 110. The springs 111 can facilitate the resetting of the squeezing plates 108 when not working, so as to facilitate the removal of the tool 105. The two mounting plates 110 drive the two anti-slip pads 109 to fix the position of the tool 105 through the two squeezing plates 108. This structure can fix the tool 105 in all directions, so that it can maintain a stable working state during the processing and improve the operating accuracy.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the cooling mechanism 2 includes a water pipe 1 201, the output end of the water pipe 1 201 is fixedly connected to a booster pump 202, the output end of the booster pump 202 is fixedly connected to a water pipe 2 203, the outer wall of the water pipe 203 is movably sleeved with a rubber fixing block 204, the output end of the water pipe 203 is fixedly connected to a nozzle 205, the top of the outer shell 101 is fixedly connected to the bottom of the booster pump 202, and the outer wall of the outer shell 101 is fixedly connected to the outer walls of the two rubber fixing blocks 204.

[0029] The effect achieved by the entire embodiment 2 is that when the temperature of the tool 105 continues to rise during the processing, external cooling water can be transported through water pipe 1 201, and then the booster pump 202 pressurizes the cooling water, and sprays the cooling water onto the surface of the tool 105 through water pipe 2 203 and the nozzle 205, quickly reducing the temperature of the tool 105, thereby reducing the wear of the tool due to high temperature, increasing the service life of the tool, and reducing the cost of replacing the tool.

[0030] Working principle: when the operator needs to install the tool 105, he only needs to insert the tool 105 into the shell 101 first. When the top of the tool 105 contacts the top of the inner wall of the shell 101, the operator can rotate the tool 105 again to drive the two baffles 103 to rotate together and insert it into the gap between the shell 101 and the two baffles 103 to complete the initial fixation of the tool 105. Then the operator can rotate the adjusting wheel 115. When the adjusting wheel 115 rotates, it will drive the bidirectional threaded rod 114 to rotate inside the circular hole 106. After the bidirectional threaded rod 114 rotates, it will drive the two ear blocks 112 to move closer to each other under the action of the surface threads. When the two ear blocks 112 move, they will drive the two mounting plates 110 below to move together, thereby squeezing the two sets of springs 111. When the two mounting plates 110 move, they will drive the two squeezing The plate 108 moves inside the two mounting holes 107 so that the two anti-skid pads 109 contact the outer wall of the tool 105, thereby fixing the tool 105 inside the housing 101. When the tool 105 is in the processing process, the temperature of the tool 105 will rise rapidly due to friction. At this time, external cooling water can be transported to the inside of the booster pump 202 through the water pipe 1 201. The booster pump 202 can pressurize the cooling water and transport it to the inside of the nozzle 205 through the water pipe 2 203. The pressurized cooling water can be quickly sprayed onto the surface of the tool 105 through the nozzle 205 to quickly reduce the temperature of the tool 105. When the tool 105 is being processed, the acoustic emission monitor 102 on the top of the housing 101 can receive the sound generated by the tool 105 during operation, thereby judging the wear of the tool 105 and reminding people to replace the severely worn tool 105 in time.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
