Technical Field

[0001] The utility model relates to the technical field of instrument processing fixtures, in particular to an instrument processing flipping fixture. Background Technique

[0002] An instrument processing fixture is a process equipment used to fix, position and clamp an instrument during the instrument processing. Its main function is to ensure that the instrument maintains the correct position and posture during processing, and prevent it from displacing or vibrating under the action of external forces such as cutting force and gravity. In terms of types, there are general fixtures that can adapt to multiple instruments, and there are also special fixtures designed for specific models of instruments.

[0003] Most traditional instrument processing flipping fixtures rely on manual adjustment of the chuck spacing to clamp the instrument, which not only consumes manpower, but also due to the differences in manual operations, it is difficult to ensure the consistency of each clamping, and it is easy to have the situation of too loose or too tight clamping, resulting in unstable instrument position during the processing, affecting the processing accuracy, and at the same time increasing the risk of human operation errors. Traditional instrument processing flipping fixtures are often designed only for instruments with specific shapes and specific installation methods, resulting in frequent replacement of fixtures when processing different types of instruments, affecting the processing efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide an instrument processing flipping fixture, which can quickly switch the instrument processing surface, meet the requirements of processing different surfaces of the instrument in complex processing processes, greatly shorten the processing cycle, and improve the overall processing efficiency.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an instrument processing flipping fixture, including an installation box, a clamping box and a clamping plate. The clamping box is rotatably arranged at one end of the installation box, and two clamping plates are slidably connected to the clamping box;

[0006] A motor and a telescopic cylinder are arranged in the installation box. A clamping component for driving the two clamping plates to slide relatively is arranged in the clamping box. The output end of the motor is connected with a rotating shaft. A hollow shaft is slidably connected to the outside of the rotating shaft. The end of the rotating shaft passes through the hollow shaft and is fixedly connected to the clamping box. The two ends of the hollow shaft are respectively connected to the telescopic cylinder and the clamping component.

[0007] Preferably, the clamping component includes a lead screw and a clamping gear. The lead screw is rotatably arranged in the clamping box. The clamping gear is fixedly arranged in the middle of the lead screw. A toothed structure meshing with the clamping gear is arranged on the outside of the hollow shaft. The clamping plate is threadedly connected to the end of the lead screw. The thread directions at both ends of the lead screw are opposite.

[0008] Preferably, a rack is fixedly connected to the outer side of the piston rod of the telescopic cylinder. A connecting shaft is rotatably arranged inside the installation box. A first gear and a second gear are rotatably connected to the connecting shaft. The rack meshes with the second gear, and a toothed structure meshing with the first gear is arranged on the outer side of the hollow shaft.

[0009] Preferably, two second gears are respectively connected to both ends of the connecting shaft, and the first gear is arranged in the middle of the connecting shaft.

[0010] Preferably, the number of teeth of the first gear is greater than that of the second gear.

[0011] Preferably, a heat dissipation cover is fixedly connected to one side of the installation box, and the installation box is communicated with the outside through the heat dissipation cover.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 , the flipping fixture for instrument processing in this embodiment includes an installation box 1, a clamping box 2 and a clamping plate 212. The clamping box 2 is rotatably arranged at one end of the installation box 1, and the two clamping plates 212 are slidably connected to the clamping box 2. A heat dissipation cover 24 is fixedly connected to one side of the installation box 1. The installation box 1 is connected to the outside through the heat dissipation cover 24, and the heat dissipation cover 24 improves the heat dissipation performance of the device.

[0027] Please refer to Figures 2 - 4, a motor 21 and a telescopic cylinder 25 are provided inside the installation box 1, a clamping assembly for driving two clamping plates 212 to slide relatively is provided inside the clamping box 2, the output end of the motor 21 is connected with a rotating shaft 22, a hollow shaft 23 is slidably connected to the outside of the rotating shaft 22, the end of the rotating shaft 22 passes through the hollow shaft 23 and is fixedly connected to the clamping box 2, both ends of the hollow shaft 23 are respectively connected with the telescopic cylinder 25 and the clamping assembly, and the telescopic cylinder 25 drives the two clamping plates 212 to move relatively through the hollow shaft 23 and the clamping assembly.

[0028] A circular through hole opened on one side of the clamping box 2 allows the hollow shaft 23 to extend into it, and the motor 21 drives the clamping box 2 and the clamping plates 212 to rotate through the rotating shaft 22.

[0029] In this embodiment, the outside of the hollow shaft 23 is a toothed structure, a rack 26 is fixedly connected to the outside of the piston rod of the telescopic cylinder 25, a connecting shaft 27 rotatably arranged is provided inside the installation box 1, a first gear 28 and a second gear 29 are rotatably connected to the connecting shaft 27, the rack 26 meshes with the second gear 29, the first gear 28 meshes with the teeth on the hollow shaft 23, the telescopic cylinder 25 drives the second gear 29 to rotate through the rack 26, and then drives the first gear 28 to rotate, thereby pushing the hollow shaft 23 to slide on the rotating shaft 22.

[0030] In this embodiment, two second gears 29 are respectively connected to both ends of the connecting shaft 27, and the first gear 28 is arranged in the middle of the connecting shaft 27 to ensure stable force on the first gear 28 and the hollow shaft 23. And the number of teeth of the first gear 28 is greater than that of the second gear 29, which can achieve the purpose of deceleration.

[0031] In other embodiments, the piston rod of the telescopic cylinder 25 can also be directly connected to the hollow shaft 23 through a connecting rod, and the structure is simpler. However, the telescopic cylinder 25 is on one side of the hollow shaft 23, and the force at the connection is uneven during the process of pushing the hollow shaft 23 to move. During repeated work, the connection between the connecting rod and the hollow shaft 23 is prone to breakage. Therefore, the telescopic cylinder 25 preferably drives the hollow shaft 23 to move by means of gears. By rotating the gears to push the hollow shaft 23 to move, the force is more balanced and the service life is longer compared with direct connection.

[0032] The clamping assembly in this embodiment includes a lead screw 210 and a clamping gear 211. The lead screw 210 is rotatably arranged inside the clamping box 2, the clamping gear 211 is fixedly arranged in the middle of the lead screw 210, the teeth on the hollow shaft 23 mesh with the clamping gear 211, the clamping plate 212 is threadedly connected to the end of the lead screw 210, and the thread directions at both ends of the lead screw 210 are opposite. Therefore, when the clamping gear 211 drives the lead screw 210 to rotate, the two clamping plates 212 can be made to move relatively.

[0033] The clamping plate 212 in this embodiment is of a T-shaped structure. A first clamping block 213 and a second clamping block 214 are fixedly connected to the inner side of the clamping plate 212. The first clamping block 213 and the second clamping block 214 are arranged perpendicular to each other, and the inner sides of both the first clamping block 213 and the second clamping block 214 are of an arc-shaped structure to facilitate clamping of a circular instrument.

[0034] Rectangular through grooves are formed in the inner sides of both the first clamping block 213 and the second clamping block 214. A clamping pad 215 is fixed inside the rectangular through groove of the first clamping block 213. The clamping pad 215 is made of rubber, which can effectively buffer during the clamping process, avoid damage such as scratching and knocking on the instrument caused by rigid contact, effectively protect the surface of the instrument, ensure the integrity of the instrument before and after processing, and improve the product yield.

[0035] The instrument can be clamped in multiple directions by the first clamping block 213 and the second clamping block 214. When the device is horizontally installed, if horizontal clamping of the instrument is required, it can be placed on one side of the first clamping block 213. When vertical clamping of the instrument is needed, it can be placed on one side of the second clamping block 214. When clamping a square instrument, it can be placed inside the rectangular through groove formed in the inner sides of the first clamping block 213 and the second clamping block 214. The rubber clamping pad 215 can prevent damage to the instrument. Through the first clamping block 213 and the second clamping block 214 vertically designed on the inner side of the clamping plate 212, it can adapt to various clamping orientation requirements such as horizontal and vertical. Whether it is different placement requirements for the instrument in the conventional installation posture or the adaptation of the square instrument using the rectangular through groove on the inner sides of the first clamping block 213 and the second clamping block 214, it greatly improves the versatility of the fixture for various instrument shapes and installation methods, and reduces the frequency of replacing the fixture due to instrument differences.

[0036] Working principle: When the user uses this device, the device can be installed at a specified position. At this time, the user can place the instrument to be clamped inside the first clamping block 213 or the second clamping block 214. At the same time, start the telescopic cylinder 25. The telescopic cylinder 25 drives the rack 26 to move towards the clamping box 2. The teeth on one side of the rack 26 drive the second gear 29 to rotate. While the second gear 29 rotates, it drives the first gear 28 fixedly connected to it to rotate. Through the first gear 28, the toothed ring structure on the outer side of the hollow shaft 23 can be continuously toggled, thereby pushing the hollow shaft 23 to slide on the rotating shaft 22. While the hollow shaft 23 moves inside the clamping box 2, it drives the clamping gear 211 to rotate through contact with the outside of the clamping gear 211. The rotation of the clamping gear 211 drives the lead screws 210 on both sides of it to rotate, thereby driving the two clamping plates 212 to move towards the middle. The rectangular through groove opened on one side of the clamping box 2 limits the movement trajectory of the clamping plate 212 to prevent it from rotating. Then, the chuck assembly on the outside of the clamping plate 212 can be used to clamp the instrument.

[0037] When the user needs to flip the instrument, start the motor 21, and the clamping box 2 and the instrument on one side of it can be flipped through the rotating shaft 22, which can quickly switch the machining surface of the instrument, meet the requirements for machining different surfaces of the instrument in complex machining processes, greatly shorten the machining cycle, and improve the overall machining efficiency. The user only needs to install the device at a specified position to carry out subsequent instrument clamping and machining work. The installation process is simple, the professional skills requirements for operators are low, it can be quickly put into use, and the equipment debugging time is reduced.

[0038] The above is only a preferred embodiment of the present invention, and it is not used to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
