Description

Technical Field

[0001] This utility model belongs to the field of temperature detection technology, specifically relating to a surface temperature detection device for a projectile. Background Technology

[0002] In the projectile assembly process, the projectile needs to be heated before loading the propellant. The projectile is placed on a pallet on the main conveyor line; when the pallet reaches the projectile surface temperature detection station, the projectile enters the anti-blast chamber for propellant loading if the temperature is qualified.

[0003] Traditional product temperature detection only requires a single temperature sensor. However, due to the special nature of projectiles and ammunition, temperature detection is necessary at multiple locations on the projectile's surface. Furthermore, it's crucial to monitor the circumferential temperature changes at different heights of the projectile to ensure they remain within acceptable limits. This detection method provides a more comprehensive understanding of the projectile's surface temperature, further improving operational safety and preventing missed detections due to localized overheating, which could lead to safety incidents.

[0004] In response to the aforementioned requirements of anti-riot operation environments, a surface temperature detection device for projectiles is provided. On the one hand, it meets the stringent requirements for temperature detection indicators; on the other hand, it replaces manual temperature detection with automated equipment, so that even if an accidental explosion occurs, there will be no casualties. Utility Model Content

[0005] In view of the problem that existing technologies cannot achieve multi-point, automated detection, the purpose of this utility model is to provide a surface temperature detection device for projectiles to solve the above problems.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A surface temperature detection device for a projectile includes two rotation drive mechanisms for driving the projectile to rotate and a temperature detection mechanism for detecting the temperature at different height positions of the projectile. A space is reserved between the two rotary drive mechanisms for placing the projectile. Each rotary drive mechanism includes at least one friction wheel. Under the action of a first external force, the friction wheel moves away from or against the surface of the projectile. Under the action of a second external force, the friction wheel rotates about its own axis. The friction wheels on the two rotary drive mechanisms rotate in the same direction. The two rotary drive mechanisms are arranged with the friction wheels facing each other. The temperature detection mechanism includes multiple temperature detectors, which are arranged at intervals in the vertical direction to correspond to temperature measurement points at different heights on the surface of the projectile.

[0007] This utility model uses a temperature detection mechanism to detect the temperature at different locations on the surface of the projectile. When the projectile is placed vertically, the temperature detection mechanism detects the temperature at different locations along the height of the projectile. Each height location that needs to be measured is monitored by a temperature detector. The rotary drive mechanism drives the projectile to rotate about its own axis. Under the drive of the rotary drive mechanism, the surface of the projectile moves relative to the temperature detection mechanism. After the projectile rotates one revolution, the temperature detector can measure the temperature change around the circumference of the projectile at that height. The driving function of the rotary drive mechanism is realized by the friction wheel. The friction wheel is in contact with the surface of the projectile. When the friction wheel rotates under the action of the second external force, it will transmit the power to the projectile in the form of friction, thereby making the projectile rotate. Only when the friction wheels of the two rotary drive mechanisms rotate in the same direction can the projectile be driven to rotate in one direction. When temperature measurement is required, to prevent the projectile from tilting under force and to ensure that the friction wheels make fuller contact with the projectile surface, the friction wheels press against the projectile surface under the action of the first external force. Since two rotary drive mechanisms are set up, the projectile is located between the two rotary drive mechanisms. When the friction wheels of both rotary drive mechanisms are in contact with the projectile, the projectile is in a stable clamping state. Each rotary drive mechanism includes at least one friction wheel, which can ensure effective clamping. If the rotary drive mechanism only has one friction wheel, then the two rotary drive mechanisms will only have a total of two friction wheels, and there will only be two points of contact with the projectile, which cannot achieve stable clamping. After the temperature measurement is completed, the direction of the first external force changes, and the friction wheel can move away from the projectile, causing the projectile to detach from the clamping state and enter the next process. In summary, this invention uses a temperature detection mechanism arranged at fixed points to measure the temperature at different heights of the projectile. A rotary drive mechanism causes relative movement of the projectile's surface relative to the temperature detection mechanism, enabling the temperature detection mechanism to measure the temperature within a circumferential range of the projectile. This broadens the detection range for projectile surface temperature measurement, providing a more accurate reflection of the projectile's surface temperature, meeting the requirements for anti-blast production, and avoiding missed detections due to localized high temperatures. Furthermore, the temperature measurement action of this invention is performed by automated components, requiring no manual intervention. Even in the event of an accident, it will not cause personnel injury, thus improving production safety.

[0008] The beneficial effects of this utility model are: 1. Temperature measurement at different heights of the projectile is achieved by using a temperature detection mechanism arranged at fixed points. A rotary drive mechanism is used to drive the surface of the projectile to move relative to the temperature detection mechanism, so that the temperature detection mechanism can measure the temperature within the circumference of the projectile. This expands the detection range when measuring the temperature of the projectile surface, more accurately reflects the surface temperature of the projectile, meets the production requirements for anti-explosion, and avoids the occurrence of missed detection of local high temperature. 2. Temperature measurement is performed by automated components without human intervention, which prevents injury or death even in the event of an accident, thus improving production safety.

[0010] The technical solution of this utility model will be described in detail below with reference to specific embodiments and accompanying drawings. The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model; these descriptions are explanatory and exemplary, and should not be construed as limiting the implementation methods or the scope of protection of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein. Example 1

[0011] As shown in the figure, this embodiment provides a surface temperature detection device for a projectile, including two rotation drive mechanisms 1 for driving the projectile DT to rotate and a temperature detection mechanism 2 for detecting the temperature at different height positions of the projectile DT. A space is reserved between the two rotary drive mechanisms 1 for placing the projectile DT. Each rotary drive mechanism 1 includes two friction wheels 13. Under the action of a first external force, the friction wheels 13 move away from or into contact with the surface of the projectile DT. Under the action of a second external force, the friction wheels 13 rotate about their own axis. The friction wheels 13 on the two rotary drive mechanisms 1 rotate in the same direction. The two rotary drive mechanisms 1 are arranged with the friction wheels 13 facing each other. The temperature detection mechanism 2 includes multiple temperature detectors 21, which are arranged at intervals in the vertical direction to correspond to temperature measurement points at different heights on the surface of the projectile DT.

[0012] In this embodiment, a temperature detection mechanism 2 is set up to detect the temperature at different positions on the surface of the projectile DT. When the projectile DT is placed vertically, the temperature detection mechanism 2 detects the temperature at different positions in the height direction of the projectile DT. Each height position that needs to be measured is monitored by a temperature detector 21. The rotary drive mechanism 1 drives the projectile DT to rotate about its own axis. Under the drive of the rotary drive mechanism 1, the surface of the projectile DT moves relative to the temperature detection mechanism 2. After the projectile DT rotates one revolution, the temperature detector 21 can measure the temperature change around the circumference of the projectile DT at that height. The driving function of the rotary drive mechanism 1 is realized by the friction wheel 13. The friction wheel 13 is in contact with the surface of the projectile DT. When the friction wheel 13 rotates under the action of the second external force, it will transmit the power to the projectile DT in the form of friction, so that the projectile DT will rotate. Only when the friction wheels 13 of the two rotary drive mechanisms 1 rotate in the same direction can the projectile DT be driven to rotate in one direction. When temperature measurement is required, in order to prevent the projectile DT from tilting under force and to ensure that the friction wheel 13 can make fuller contact with the surface of the projectile DT, the friction wheel 13 presses against the surface of the projectile DT under the action of the first external force. Since two rotary drive mechanisms 1 are set up, the projectile DT is located between the two rotary drive mechanisms 1. When the friction wheels 13 of both rotary drive mechanisms 1 are in contact with the projectile DT, the projectile DT is in a stable clamping state. Each rotary drive mechanism 1 includes at least two friction wheels 13, which can ensure effective clamping. If the rotary drive mechanism 1 has only one friction wheel 13, then the two rotary drive mechanisms 1 will only have a total of two friction wheels 13. When in contact with the projectile DT, there will only be two points of contact, and stable clamping cannot be achieved. After the temperature measurement is completed, the direction of the first external force changes, and the friction wheel 13 can move away from the projectile DT, so that the projectile DT can be released from the clamping state and enter the next process. In summary, this invention uses a temperature detection mechanism 2 arranged at fixed points to measure the temperature at different heights of the projectile DT. A rotary drive mechanism 1 drives the surface of the projectile DT to move relative to the temperature detection mechanism 2, enabling the temperature detection mechanism 2 to measure the temperature within the circumference of the projectile DT. This broadens the detection range for measuring the surface temperature of the projectile DT, providing a more accurate reflection of the surface temperature, meeting the requirements for anti-blast production, and avoiding missed detections due to localized high temperatures. Furthermore, the temperature measurement action of this invention is performed by automated components, requiring no manual intervention. Even in the event of an accident, it will not cause personnel injury, thus improving production safety. Example 2

[0013] As shown in the figure, this embodiment provides a surface temperature detection device for a projectile. The difference from embodiment 1 is that the temperature detection mechanism 2 also includes a mounting base 22 corresponding to the number of temperature detectors 21 and a vertically arranged bracket 23. The mounting base 22 is used to fix the temperature detectors 21. The mounting base 22 is fixed at a height position that matches the bracket 23 according to the temperature measurement height requirements.

[0014] In some optional examples, the mounting base 22 is provided with a threaded hole for mating with the temperature detector 21, which is used to achieve a threaded connection with the temperature detector 21. The mounting base 22 is also provided with a through hole for sliding connection with the bracket 23, and a gap is formed through the through hole by the indentation. When the gap closes under the action of external force, the external force can force the mounting base 22 to deform, thereby reducing the range of the through hole and pressing the mounting base 22 onto the bracket 23. Then, the mounting base 22 is fixed on the bracket 23 by friction. The mechanism for forcing the mounting base 22 to deform can be implemented by bolts and nuts. The bolt passes through the mounting base 22 and is tightened with the nut, thereby compressing the mounting base 22 to deform and the gap closes. Since there are many ways to fix the temperature detector 21 and the mounting base 22 to the bracket 23, other fixing structures can also be used to fix the temperature detector 21 and the mounting base 22.

[0015] In this embodiment, a structure for fixing the temperature detector 21 is specifically defined. The bracket 23 is used to provide a vertical mounting base, and the mounting base 22 provides a mounting base for the temperature detector 21. The mounting base 22 can be moved up and down relative to the bracket 23 to adjust the temperature measurement height of the temperature detector 21. Example 3

[0016] As shown in the figure, this embodiment provides a surface temperature detection device for a projectile. The difference from embodiment 1 is that the rotary drive mechanism 1 further includes a clamping plate 11 that provides an installation position for the friction wheel 13. The clamping plate 11 is provided with a slot for accommodating the projectile DT and avoiding interference.

[0017] In this embodiment, a clamping plate 11 is specifically defined. The clamping plate 11 can provide an installation position for the friction wheel 13. However, the setting of the clamping plate 11 will cause some interference to the friction wheel 13 clamping the projectile DT. In order to solve this problem, the clamping plate 11 has a slot at the position corresponding to the projectile DT, so as to avoid the projectile DT and prevent interference. Example 4

[0018] As shown in the figure, this embodiment provides a surface temperature detection device for a projectile. The difference from embodiment 3 is that the rotary drive mechanism 1 further includes a guide mechanism for guiding the clamping plate 11. The guide mechanism consists of a guide rod 17 and a guide seat 18, and the guide rod 17 and the guide seat 18 are in sliding engagement.

[0019] In this embodiment, a guiding mechanism is specifically defined. This guiding mechanism is mainly used to regulate and stabilize the movement of the clamping plate 11, so that the friction wheel 13 on the clamping plate 11 can accurately contact the projectile DT. Example 5

[0020] As shown in the figure, this embodiment provides a surface temperature detection device for a projectile. The difference from embodiment 3 is that the rotary drive mechanism 1 further includes a first power source 16 for providing a first external force. The first power source 16 is any one of a cylinder, hydraulic cylinder, or electric cylinder. The output end of the first power source 16 is connected to the clamping plate 11, thereby driving the clamping plate 11 away from or closer to the projectile DT. The rotary drive mechanism 1 also includes a motor 14 for providing a second external force. The motor 14 is fixed on the clamping plate 11 and moves with the clamping plate 11. An active synchronous wheel 15 is installed at the output end of the motor 14. The clamping plate 11 is rotatably connected to a passive synchronous wheel 12. The active synchronous wheel 15 and the passive synchronous wheel 12 are connected by a synchronous belt. The number of passive synchronous wheels 12 is adapted to the number of friction wheels 13. The passive synchronous wheels 12 drive the friction wheels 13 to rotate together through a rotating shaft.

[0021] In this embodiment, the second external force is specifically provided by a motor 14, and is transmitted to the friction wheel 13 through an active synchronous pulley 15, a passive synchronous pulley 12, and a synchronous belt. This method ensures that the multiple friction wheels 13 move in unison. Specifically, the motor 14 drives the active synchronous pulley 15 to rotate, the active synchronous pulley 15 transmits power to the synchronous belt, the synchronous belt transmits power to the passive synchronous pulley 12, and the passive synchronous pulley 12 then drives the friction wheel 13 to rotate. The motor 14 is easy to control in terms of speed and direction, and its electrical energy is readily available. The first power source 16 that provides the first external force is specifically defined. The first power source 16 can be any one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. Since different power forms have different characteristics, for example, the air source of a pneumatic cylinder is easy to obtain and the pneumatic cylinder is easy to control and maintain, while the hydraulic cylinder has greater power, and the electric cylinder is easy to automate and precisely control. Depending on the actual use and working conditions, a suitable first power source 16 that provides the first external force can be selected. Example 6

[0022] As shown in the figure, this embodiment provides a surface temperature detection device for a projectile. The difference from embodiment 5 is that the passive synchronous wheel 12 is rotatably connected to the clamping plate 11 through a seated bearing and a rotating shaft. The rotating shaft is fixed to the inner ring of the bearing, and the outer ring of the bearing is fixedly connected to the clamping plate 11. Both ends of the rotating shaft extend out of the clamping plate 11. The passive synchronous wheel 12 is installed at one end of the rotating shaft, and the friction wheel 13 is installed at the other end.

[0023] In this embodiment, the power transmission structure of the passive synchronizing wheel 12 and the friction wheel 13 is specifically defined. The two transmit power through a rotating shaft, which is mounted with a bearing, and the bearing is fixed on the clamping plate 11.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
