Description

Technical Field

[0001] The utility model relates to the technical field of laser gyroscope processing, in particular to a workpiece clamping device for laser gyroscope cavity processing. Background Art

[0002] During the manufacturing process of a laser gyroscope, the machining accuracy of the cavity is crucial to the instrument's performance stability and measurement accuracy. The core components of a laser gyroscope require high-precision machining, including the smoothness of the cavity interior and the sealing of all connecting surfaces. This places extremely high demands on the clamping and fixing of the workpiece.

[0003] Traditional workpiece clamping devices mostly use mechanical clamps, but mechanical clamps are prone to stress concentration on the workpiece surface, thereby affecting the surface quality of the cavity. In addition, due to the complex processing shape of the laser gyroscope cavity, the clamps are often unable to achieve efficient clamping, resulting in insufficient stability of the workpiece during processing, affecting process consistency. The existing clamping devices are complicated to operate when changing workpieces or adjusting positions, and different types of cavities often require special clamps, which increases the cost of using the equipment and the difficulty of maintenance. For this reason, there are now suction cups on the market that are set between the clamping plate and the flange, which can be used to perform multiple precision processing on the laser gyroscope cavity without the need for multiple clamping and adjustment operations.

[0004] However, after the processing operation is completed, the laser gyroscope cavity and the clamping plate are still adsorbed by the suction cup, and complex operation steps are required to separate the two, which leads to problems such as increased operation time and reduced processing efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a laser gyroscope cavity processing workpiece clamping device.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0007] A laser gyroscope cavity processing workpiece clamping device includes a drive motor with a drive shaft and a laser gyroscope cavity, and also includes a flange and a clamping plate. The flange and the clamping plate are both hollow annular structures, and the flange and the clamping plate are respectively coaxially sleeved with the drive shaft. A gap for installing the laser gyroscope cavity is provided between the flange and the clamping plate. Multiple groups of suction cups are arranged around the side of the clamping plate facing the flange. An air cavity connected to the suction cup is provided inside the clamping plate. An exhaust port connected to the air cavity is provided on the clamping plate, and a closing plate for closing the exhaust port is provided on the exhaust port.

[0008] Furthermore, multiple groups of suction cups are arranged at equal intervals around the circumference. These equally spaced suction cups provide uniformly distributed clamping force around the laser gyroscope cavity, avoiding stress concentration on the workpiece surface caused by localized uneven force, effectively protecting the cavity's surface flatness and integrity, and thus improving processing quality. Furthermore, this uniform suction distribution enhances cavity stability, preventing vibration or deviation during processing.

[0009] Furthermore, any set of the suction cups includes two independent suction cups, which are arranged radially along the side of the pressing plate. The two suction cups enable the adsorption force to cover the inner and outer diameter areas of the laser gyroscope cavity, achieving more uniform radial clamping.

[0010] Furthermore, the two independent suction cups include an outer ring suction cup and an inner ring suction cup, and the diameter of the outer ring suction cup is greater than or equal to the diameter of the inner ring suction cup. The outer ring suction cup and the inner ring suction cup can cover laser gyroscope cavities of different diameters, thereby adapting to laser gyroscope cavities of different models. For larger-sized laser gyroscope cavities, the outer ring suction cup provides the main clamping force, and the inner ring suction cup provides the auxiliary clamping force. For smaller-sized laser gyroscope cavities, the inner ring suction cup is independently adsorbed, and the smaller inner ring suction cup diameter can be more suitable for small-sized laser gyroscope cavities.

[0011] Furthermore, the exhaust port is arranged on a side away from the suction cup, and two exhaust ports are provided. When the laser gyroscope cavity needs to be clamped, the exhaust port is in a closed state, and the negative pressure is transmitted to the surface of the workpiece through the suction cup connected to the air cavity. The suction cup adheres to the surface of the cavity and generates adsorption force to fix the workpiece. When the processing is completed, the exhaust port needs to be opened to allow external air to quickly enter the air cavity and eliminate the negative pressure in the air cavity. The internal and external air pressures are balanced, the adsorption force in the suction cup disappears, and the workpiece can be easily removed. The two exhaust ports can speed up the exhaust speed of the air cavity, which helps to quickly release the negative pressure of the clamping device when the adsorption is released.

[0012] Furthermore, a silicone soft film is provided on one side of the closing plate corresponding to the exhaust port. The silicone soft film solves the problem of insufficient sealing of the sealing material and improves the durability and fatigue resistance of the material, making it suitable for long-term use.

[0013] Furthermore, the closing plate and the pressing disc are rotatably connected via a rotating shaft or a hinge.

[0014] Furthermore, the movable end of the closing plate is snap-fitted to the pressing plate, which facilitates quick opening or closing of the closing plate and improves operating efficiency during processing.

[0015] Furthermore, the free end of the drive shaft is provided with threads, which are mated with a nut. The locking action of the nut secures the laser gyroscope cavity between the flange and the pressure plate, thereby improving clamping stability. This threaded connection facilitates workpiece installation and removal, enhancing the operational efficiency and flexibility of the device.

[0016] Furthermore, the flange and the drive shaft have an interference fit. An interference fit refers to a slight difference in the matching dimensions between the flange and the drive shaft, which enables a strong clamping force during assembly. This clamping force ensures a more secure connection between the flange and the drive shaft, preventing loosening or displacement during operation, thereby improving the stability of the entire clamping device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The utility model controls the adsorption and release of the suction cup by closing the exhaust port through a closing plate, and can quickly separate the workpiece and the pressing plate without complicated disassembly or adjustment operations, thereby reducing the operation time of the separation step and improving production efficiency;

[0019] 2. The utility model can adapt to different types of laser gyroscope cavities by arranging outer ring suction cups and inner ring suction cups with different radii on the pressing plate, and can also further enhance the adsorption capacity and improve the stability during processing;

[0020] 3. The utility model realizes the firm adsorption of the laser gyroscope cavity, while avoiding the stress concentration problem that may be caused by traditional mechanical fixtures, ensuring the stability of workpiece clamping and the smoothness of the cavity surface, and improving the processing accuracy.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0026] Example 1, as Figure 1-3 As shown, the utility model discloses a laser gyroscope cavity processing workpiece clamping device, including a driving motor 1 with a driving shaft 2 and a laser gyroscope cavity 3, and also includes a flange 4 and a clamping plate 5. The flange 4 and the clamping plate 5 are both hollow annular structures, and the flange 4 and the clamping plate 5 are respectively coaxially sleeved with the driving shaft 2. A gap for installing the laser gyroscope cavity 3 is provided between the flange 4 and the clamping plate 5, and a plurality of groups of suction cups 6 are arranged around the side of the clamping plate 5 facing the flange 4. An air cavity connected to the suction cup 6 is provided inside the clamping plate 5, and an exhaust port 7 connected to the air cavity is provided on the clamping plate 5, and a closing plate 8 for closing the exhaust port 7 is provided on the exhaust port 7.

[0027] Multiple groups of suction cups 6 are arranged at equal intervals around the circumference. Specifically, these equally spaced suction cups 6 provide uniformly distributed clamping force around the laser gyroscope cavity 3, avoiding stress concentration on the workpiece surface or structure caused by localized uneven force, effectively protecting the flatness and integrity of the cavity surface, and thus improving processing quality. Furthermore, this uniform suction distribution enhances cavity stability, preventing vibration or deviation during processing.

[0028] Any set of suction cups 6 includes two independent suction cups 6, which are arranged radially along the side of the pressing plate 5. Specifically, the two suction cups 6 enable the adsorption force to cover the inner and outer diameter areas of the laser gyroscope cavity 3, achieving more uniform radial clamping.

[0029] The two independent suction cups 6 include an outer ring suction cup and an inner ring suction cup, and the diameter of the outer ring suction cup is greater than or equal to the diameter of the inner ring suction cup. Specifically, the outer ring suction cup and the inner ring suction cup can cover laser gyroscope cavities 3 of different diameters, thereby adapting to laser gyroscope cavities 3 of different models. For larger-sized laser gyroscope cavities 3, the outer ring suction cup provides the main clamping force, and the inner ring suction cup provides the auxiliary clamping force. For smaller-sized laser gyroscope cavities 3, the inner ring suction cup is independently adsorbed, and the smaller inner ring suction cup diameter can be more suitable for small-sized laser gyroscope cavities 3.

[0030] The exhaust port 7 is provided on a side away from the suction cup 6, and two exhaust ports 7 are provided. Specifically, when the laser gyroscope cavity 3 needs to be clamped, the exhaust port 7 is in a closed state, and the negative pressure is transmitted to the surface of the workpiece through the suction cup 6 connected to the air cavity. The suction cup 6 adheres to the surface of the cavity and generates an adsorption force to firmly fix the workpiece. When the processing is completed, the exhaust port 7 needs to be opened to allow external air to quickly enter the air cavity and eliminate the negative pressure in the air cavity. The internal and external air pressures are balanced, and the adsorption force in the suction cup 6 disappears, and the workpiece can be easily removed. The two exhaust ports 7 can speed up the exhaust speed of the air cavity, which helps to quickly release the negative pressure of the clamping device when the adsorption is released.

[0031] The side of the closing plate 8 corresponding to the exhaust port 7 is provided with a silicone soft film. Specifically, the silicone soft film solves the problem of insufficient sealing of the sealing material, and at the same time improves the durability and fatigue resistance of the material, and can adapt to long-term use.

[0032] The closing plate 8 is rotatably connected to the pressure plate 5 via a rotating shaft or a hinge.

[0033] The movable end of the closing plate 8 is snap-fitted to the pressing plate 5. Specifically, the snap-fitting connection facilitates rapid opening or closing of the closing plate 8, thereby improving operating efficiency during processing.

[0034] The free end of the drive shaft 2 is provided with threads, which are mated with a nut 9. Specifically, the locking action of the nut 9 securely secures the laser gyroscope cavity 3 between the flange 4 and the pressure plate 5, thereby improving clamping stability. The threaded connection facilitates workpiece installation and removal, enhancing the operational efficiency and flexibility of the equipment.

[0035] The flange 4 and the drive shaft 2 have an interference fit. Specifically, an interference fit refers to a slight difference in the matching dimensions between the flange 4 and the drive shaft 2, which enables a strong tightening force to be generated during assembly. This tightening force ensures a more stable connection between the flange 4 and the drive shaft 2, preventing loosening or displacement during operation, thereby improving the stability of the entire clamping device.

[0036] Embodiment 2: Based on embodiment 1, this embodiment proposes a specific working principle of a workpiece clamping device for laser gyroscope cavity processing.

[0037] The specific implementation principle process is as follows:

[0038] Clamp the laser gyroscope cavity 3 between the flange 4 and the pressure plate 5. Start the drive motor 1, which drives the shaft 2 to rotate the flange 4 and pressure plate 5. When the suction cup 6 of the pressure plate 5 contacts the cavity surface, negative pressure is generated, ensuring that the suction cup 6 provides sufficient clamping force on the laser gyroscope cavity 3, thereby ensuring stable control of the lifting during the processing. After processing is completed, open the exhaust port 7 to allow air to enter the air cavity. The negative pressure in the air cavity is released, and the suction force of the suction cup 6 disappears, allowing the laser gyroscope cavity 3 to be easily removed.

[0039] Of course, the present invention may have many other implementation methods. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
