Description

Technical Field

[0001] The invention belongs to the technical field of mechanical design, and particularly relates to an adjustable attitude cabin locking mechanism and method. Background Art

[0002] In the aerospace field, the cabin of a missile integrates many functions such as guidance, control, navigation, and scheduling, and is the core component of the missile. Therefore, multiple parts need to be installed inside the cabin. However, during the installation of parts inside the missile cabin, due to the excessive number of parts to be installed and different installation angles, the cabin needs to be fixed during the installation of parts inside the cabin, and the angle of the cabin needs to be adjusted arbitrarily according to the installation needs of workers.

[0003] The current locking mechanism of the missile cabin can only lock the cabin with a fixed diameter and fixed length, and the angle of the cabin cannot be automatically adjusted during the locking process, and can only be manually adjusted. This locking mechanism reduces the work efficiency of workers and can only be applied to manual assembly and cannot be used for automated assembly. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the invention provides an adjustable attitude cabin locking mechanism and method. The mechanism mainly consists of a linear guide rail, a motor assembly, a base, and a rolling ring. The linear guide rail supports the whole and enables the base to slide on the guide rail, thereby adjusting the front and rear positions of the cabin. A rolling ring is placed on the upper end of the base, and a motor is installed on the side. The motor is engaged with the front gear of the driving ring of the rolling ring through an electromagnetic clutch, and is responsible for providing power to drive the driving ring to rotate, thereby adjusting the attitude of the cabin. The electromagnetic clutch can also be disengaged to cut off the power transmitted by the motor, thereby manually adjusting the attitude of the cabin. Four countersunk holes are evenly machined on the outer surfaces of the driving ring and the driven ring. The ends of the countersunk bolts are fixedly connected with four arc-shaped clamping blocks. By tightening or loosening the bolts, the arc-shaped clamping blocks can be controlled to move forward or backward along the center of the driving ring and the driven ring, thereby clamping cabins with different diameters. Both the driving ring and the driven ring are fixed to the sliding table of the linear guide rail through the base, and the axial distance between the driving ring and the driven ring can be adjusted arbitrarily. Therefore, this mechanism can lock any cabin within a certain range of diameter and a certain range of length, and the attitude can be adjusted, greatly expanding the application range of the cabin locking device and improving the work efficiency.

[0005] The technical solution adopted by the invention to solve its technical problems is as follows:

[0006] An adjustable attitude cabin locking mechanism includes a linear guide rail, a base, a rolling ring, and a motor assembly;

[0007] The linear guide rail includes a guide rail, a slider, and rolling elements; the guide rail is fixed on the working surface; the slider straddles the guide rail through a chute provided at the bottom, and rolling elements are assembled inside the slider; the rolling elements include ball bearings and rollers, which roll between the guide rail and the slider to reduce friction;

[0008] A groove is machined at the end of the base; a connecting block for fixed connection is provided on the slider, which cooperates with the groove at the end of the base and is fixed by threads; two rollers are installed at the left and right ends of the base through brackets, and the rollers are in contact with the rolling ring to provide support;

[0009] The rolling ring includes a driving ring and a driven ring; both the driving ring and the driven ring are composed of an upper half ring and a lower half ring. Through holes are machined at the left and right ends of the upper half ring and the lower half ring. The upper half ring and the lower half ring are connected by countersunk head bolts and nuts. Two arc-shaped clamping blocks are arranged inside the upper half ring and the lower half ring respectively to lock the cabin body;

[0010] The motor assembly includes a motor, a motor bracket, an electromagnetic clutch, and an encoder; the motor is fixed in the center of the base through the motor bracket, and the motor shaft meshes with the teeth of the driving ring through the electromagnetic clutch; the encoder is installed at the end of the motor shaft, rotates with the motor, and records the position of the motor at all times;

[0011] The end of the driving ring of the rolling ring has a protruding part, which is machined into a gear and meshes with the gear at the end of the motor shaft. The motor provides power to drive the driving ring to rotate.

[0012] Preferably, the number of teeth of the electromagnetic clutch is 17, the number of teeth of the driving ring gear is 85, and the transmission ratio is 1:5.

[0013] Preferably, four countersunk holes are machined on the outer surfaces of both the driving ring and the driven ring, and four arc-shaped clamping blocks are connected by countersunk head bolts to lock the cabin body.

[0014] Preferably, the arc-shaped clamping block is fixedly connected to the end of the countersunk head bolt. The size of the countersunk head bolt is M6, its pitch is 0.5 mm, and its length is 40 mm. Initially, it locks the cabin body with a diameter of 300 mm. When the bolt rotates one week, it can drive the arc-shaped clamping block to move forward 0.5 mm. At this time, it can lock the cabin body with a diameter 1 mm smaller.

[0015] Preferably, the countersunk head bolt can only rotate an integer number of turns; the maximum distance of the countersunk head bolt moving along the axis is 20 mm. Therefore, the cabin body locking mechanism can lock any cabin body with an integer diameter less than 300 mm and greater than 260 mm.

[0016] Preferably, a groove is machined in the middle of the base to cooperate with the motor bracket.

[0017] Preferably, the motor bracket is processed into a groove shape, connected to the base at both left and right ends, and provides support for the motor.

[0018] Preferably, rollers are installed at the left and right ends of the base. The inner diameter of the roller is larger than the diameter of its support shaft, which belongs to a clearance fit. Therefore, the roller can rotate freely around its axis.

[0019] Preferably, when the motor is braked, the end gear of the motor locks the driving ring of the locking ring, and the locking ring is fixed. At this time, the roller provides support for the locking ring. When the motor rotates to drive the locking ring to rotate, the roller rotates accordingly, thereby reducing friction.

[0020] An operation method of an adjustable attitude cabin locking mechanism includes the following steps:

[0021] Step 1: The base is fixedly connected to the slider of the linear guide through screws and moves with the slider. The motor is connected to the base through the bracket by bolts and screws.

[0022] Step 2: Measure the diameter of the cabin to be locked. Adjust the axial feed of the countersunk head bolts on the arc-shaped clamping block according to the diameter of the cabin to ensure that the cabin can be locked through the slider. The axial feeds of all countersunk head bolts are the same, which can ensure that the cabin and the locking ring are concentric.

[0023] Step 3: Brake the motor, place the lower half rings of the driving ring and the driven ring on the base, and the rollers of the base contact the outer surface of the lower half ring to provide support.

[0024] Step 4: Place the cabin on the locking ring, adjust the distance between the lower half ring of the driving ring and the lower half ring of the driven ring according to the length of the cabin to make the locking of the locking ring on the cabin reach the best state. After the position is determined, fix it through the screws on the side of the slider on the guide rail.

[0025] Step 5: Fit the upper half rings and the lower half rings of the driving ring and the driven ring, and lock them through screws and bolts.

[0026] Step 6: The cabin locking is completed. The motor is powered on and rotates, driving the driving ring of the locking ring to rotate. The driving ring drives the driven ring to rotate through the cabin, thereby automatically adjusting the attitude of the cabin.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. The position of the arc-shaped clamping block inside the rolling ring of the present invention is adjustable.

[0030] 2. Both the driving ring and the driven ring of the rolling ring of the present invention are installed on the slider of the guide rail through the base, and the axial distance between the driving ring and the driven ring can be adjusted arbitrarily according to needs. Compared with the previous locking mechanism, the application range is expanded;

[0031] 3. A gear is machined at the end of the driving ring of the present invention, and a servo motor is installed on the base.

[0040] The present invention will be further described below with reference to the drawings and embodiments.

[0041] In order to solve the problems of low working efficiency and small application range of the current cabin locking mechanism, the present invention proposes a cabin locking mechanism with adjustable attitude.

[0042] The technical solution of the present invention is as follows: An adjustable attitude cabin locking mechanism, which includes a linear guide rail, a base, a rolling ring and a motor assembly; The linear guide rail mainly includes three parts: a guide rail, a slider and rolling elements. The guide rail is fixed to the working surface by screws. The slider straddles the guide rail through a chute provided at the bottom. Rolling elements, balls and rollers, are assembled inside the slider and roll between the guide rail and the slider to reduce friction; A groove is machined at the end of the base. A connecting block for fixed connection is provided on the slider of the linear guide rail and is matched with the groove at the end of the base and fixed by threads. Two rollers are installed at the left and right ends of the base through brackets. The rollers are in contact with the rolling ring to provide support;

[0043] Both the driving ring and the driven ring of the rolling ring are composed of an upper half ring and a lower half ring. Through holes are machined at the left and right ends of the upper half ring and the lower half ring. The upper half ring and the lower half ring are connected by countersunk bolts and nuts. Two arc-shaped clamping blocks are arranged inside each of the upper half ring and the lower half ring to lock the cabin;

[0044] The motor assembly consists of four parts: a motor, a motor bracket, an electromagnetic clutch and an encoder. The motor is fixed at the center of the base through the motor bracket at a suitable position. The motor shaft meshes with the teeth of the driving ring through the electromagnetic clutch. The encoder is installed at the end of the shaft, rotates with the motor, and records the position of the motor at all times;

[0045] There is a protruding part at the end of the driving ring of the rolling ring. The protruding part is machined into a gear and meshes with the gear at the end of the motor shaft. The motor provides power to drive the driving ring to rotate;

[0046] The electromagnetic clutch has 17 teeth, the driving ring gear has 85 teeth, and the transmission ratio is 1:5. The transmission ratio is relatively small. Therefore, when the rolling ring rotates at a low speed, the motor can rotate at a high speed, and the working efficiency of the motor is relatively high;

[0047] Four countersunk holes are machined on the outer surfaces of both the driving ring and the driven ring. Four arc-shaped clamping blocks are connected by countersunk bolts to lock the cabin;

[0048] The arc-shaped clamping block is fixed to the end of the countersunk bolt. The size of the countersunk bolt is M6, its pitch is 0.5mm, and its length is 40mm. Initially, it can lock a cabin with a diameter of 300mm. When the bolt rotates one week, it can drive the arc-shaped clamping block to move forward 0.5mm. At this time, it can lock a cabin with a diameter 1mm smaller;

[0049] Since the arc-shaped clamping block is arc-shaped, when locking the cabin body, it is necessary to ensure that the surface of the arc-shaped clamping block is parallel to the surface of the rolling ring. Therefore, the countersunk head bolt can only be rotated by an integer multiple of turns, and the maximum distance of the countersunk head bolt moving along the axial direction is 20 mm. Therefore, this device can basically lock the cabin body with any integer diameter less than 300 mm and greater than 260 mm. However, since most cabin bodies are standard parts and their diameters are all integers, this device can basically lock any cabin body with a diameter between 260 mm and 300 mm;

[0050] A groove is machined in the middle of the base to cooperate with the motor bracket;

[0051] The motor bracket is machined into a groove shape, and its left and right ends are connected to the base to provide support for the motor. The motor is fixed to the motor bracket through the front flange, the motor shaft passes through the motor bracket, and is matched with the front gear of the driving ring through an electromagnetic clutch.

[0052] Rollers are installed at the left and right ends of the base. The inner diameter of the roller is larger than the diameter of its support shaft, which is an interference fit. Therefore, the roller can rotate freely around its axis;

[0053] When the motor brakes, the end gear of the motor locks the driving ring of the rolling ring, and the rolling ring is fixed. At this time, the roller provides support for the rolling ring. When the motor rotates to drive the rolling ring to rotate, the roller can rotate accordingly, thereby reducing friction;

[0054] The rolling ring can automatically adjust the attitude of the cabin body through the motor, and can be applied to automatic assembly. It is also possible to disconnect the electromagnetic clutch, cut off the power connection between the motor and the rolling ring, and manually rotate the rolling ring to control the attitude of the cabin body;

[0055] An operation method for an adjustable attitude cabin body locking mechanism includes the following steps:

[0056] Step 1: The base is fixedly connected to the slider of the linear guide through screws and moves with the slider. The motor is connected to the base through the bracket by bolts and screws;

[0057] Step 2: Measure the diameter of the cabin body to be locked, and adjust the axial feed of the countersunk head bolts on the arc-shaped clamping block according to the diameter of the cabin body to ensure that the cabin body can be locked through the slider. The axial feeds of each countersunk head bolt are the same, which can ensure that the cabin body and the rolling ring are concentric.

[0058] Step 3: Brake the motor, place the lower half rings of the driving ring and the driven ring on the base, and the rollers of the base contact the outer surface of the lower half ring to provide support;

[0059] Step 4: Place the cabin body on the rolling ring, adjust the distance between the lower half ring of the driving ring and the lower half ring of the driven ring according to the length of the cabin body to make the locking of the rolling ring on the cabin body reach the best state. After the position is determined, fix it through the screws on the side of the slider on the guide rail;

[0060] Step Five: Mate the upper and lower half rings of the driving ring and the driven ring, and lock them with screws and bolts.

[0061] Step Six: After the cabin is locked, the motor is powered on and rotates, driving the driving ring of the rolling ring to rotate. The driving ring drives the driven ring to rotate following it through the cabin, thereby automatically adjusting the attitude of the cabin.

[0062] Step Seven: The electromagnetic clutch is disengaged, and the worker can manually adjust the attitude of the cabin.

[0063] Embodiment:

[0064] The current locking mechanism of the missile cabin can only lock cabins with a fixed diameter and length, and there is no power device, so it cannot be used for automatic assembly. To address these problems, the present invention proposes a locking mechanism for a missile cabin with adjustable attitude. Referring to Figures 1 to 7 , this mechanism includes four parts: a linear guide rail, a base, a rolling ring, and a motor assembly.

[0065] As Figure 2 shown, the linear guide rail includes a guide rail, rolling elements, and a slider. The slider straddles the slide rail through a chute provided at the bottom and moves reciprocally on the slide rail through the rolling elements, thereby reducing friction.

[0066] As Figure 3 shown, grooves are machined on the left and right sides of the lower surface of the base to cooperate with the connecting parts on the slide table of the linear guide rail. The base and the slide table are fixed with bolts. The base can move left and right driven by the slide table, so it can lock cabins with a length within a certain range. A groove is machined in the middle of the base to cooperate with the motor bracket to ensure that the motor can be fixed at the center of the base. Roller brackets and rollers are added to the upper parts of the left and right ends of the base respectively. The roller brackets and the base are fixed by threaded connection. The diameter of the shaft of the roller bracket is smaller than the diameter of the hole of the roller, which is an interference fit. Therefore, the roller can rotate freely along the shaft of the roller bracket. At the same time, in order to reduce the weight of the base, a lightweight design is carried out, and the left and right sides of the base are each hollowed out to machine two square through holes.

[0067] As Figure 4 and Figure 5As shown in the figure, the rolling ring is divided into a driving ring and a driven ring. The only difference between the driving ring and the driven ring is that there is an additional gear at the end of the driving ring, which can cooperate with the electromagnetic clutch at the end of the motor shaft. Thus, the driving ring is pushed to rotate under the drive of the motor to automatically adjust the attitude of the cabin. The rolling ring is divided into an upper half ring and a lower half ring. Through holes are processed at the left and right ends of the upper half ring and the lower half ring, and the two are connected by screws and bolts. Two arc-shaped clamping blocks are fixedly connected inside the upper half ring and the lower half ring respectively by countersunk bolts. By tightening or loosening the countersunk bolts, the arc-shaped clamping blocks can be controlled to move forward or backward along the center of the rolling ring, so as to lock the cabin with multiple diameters. The pitch of the countersunk bolt is 0.5 mm. When it rotates one circle, it can control the arc-shaped clamping block to move forward or backward by 0.5 mm while rotating. The diameter of the cabin that can be locked will increase or decrease by 1 mm. Since the outer surface of the arc-shaped clamping block needs to be parallel to the surface of the rolling ring when locking the cabin, the number of turns of the countersunk bolt rotation can only be an integer multiple. This device can only lock the cabin with an integer diameter. However, since the cabin is generally a standard part and its diameter is mostly an integer, this device can lock any cabin within a certain diameter range;

[0068] As Figure 6 shown in the figure, the motor assembly consists of four parts: a motor bracket, a motor, an electromagnetic clutch, and a motor encoder. The motor bracket is fitted with the middle groove of the base and fixed together by threaded connection. The motor is fixed to the motor bracket through the front flange. The motor shaft is meshed with the gear of the driving ring through the electromagnetic clutch to drive the driving ring to rotate and automatically adjust the attitude of the cabin. The electromagnetic clutch can also be disengaged, and the worker can manually adjust the attitude of the cabin.

[0069] The rollers at the end of the base contact the rolling ring to provide support for the rolling ring. At the same time, the rollers can rotate freely and follow the rolling ring to rotate when the rolling ring rotates, thus reducing friction.

[0070] When using the mechanism of the present invention to lock the missile cabin, the steps are as follows;

[0071] Step 1: The base is fixedly connected to the slider of the linear guide through screws and moves with the slider. The motor is connected to the base through the bracket by bolts and screws;

[0072] Step 2: Measure the diameter of the cabin to be locked, and adjust the axial feed of the countersunk bolts on the arc-shaped clamping blocks according to the diameter of the cabin to ensure that the cabin can be locked through the slider. The axial feeds of each countersunk bolt are the same, which can ensure that the cabin and the rolling ring are concentric.

[0073] Step 3: Brake the motor, place the lower half rings of the driving ring and the driven ring on the base, and the rollers of the base contact the outer surface of the lower half ring to provide support;

[0074] Step 4: Place the cabin on the rolling ring, adjust the distance between the lower half of the driving ring and the lower half of the driven ring according to the length of the cabin to achieve the best locking state of the rolling ring on the cabin. After the position is determined, fix it with the screws on the side of the slider on the guide rail;

[0075] Step 5: Fit the upper half and the lower half of the driving ring and the driven ring, and lock them with screws and bolts;

[0076] Step 6: After the cabin is locked, the motor is powered on and rotates, driving the driving ring of the rolling ring to rotate. The driving ring drives the driven ring to rotate following through the cabin, so as to automatically adjust the attitude of the cabin;

[0077] Step 7: The electromagnetic clutch is disengaged, and the worker can manually adjust the attitude of the cabin.
