Description

Technical Field

[0001] The utility model belongs to the technical field of the locking front ring assembly of an SF6 density controller, and particularly relates to a clamping device for the locking front ring of a remote transmission type SF6 density controller. Background Technique

[0002] In a remote transmission type SF6 density controller, the correct assembly position of the locking front ring is crucial, which directly affects the sealing performance, stability of the device, and the protection of internal parts. The assembly position of the locking front ring is usually located at the front end of the meter housing, that is, between the dial and the electronic part.

[0003] The assembly of the locking front ring mainly relies on manual operation. According to the design scheme of the remote transmission type SF6 density controller, first, the SF6 density controller is manually placed and fixed on a three-jaw chuck, and then the rocker of the three-jaw chuck is manually rotated to gradually close the jaws of the three-jaw chuck to clamp the SF6 density controller. Then, the locking front ring is sleeved, and a special tool such as a torque wrench is used to fasten the locking front ring according to the specified torque value. This method of clamping by relying on a three-jaw chuck not only has low efficiency, but mainly because manually rotating the rocker to gradually close the jaws cannot control the clamping force of the three-jaw chuck, which easily causes the SF6 density controller to loosen and deflect when fixing the locking front ring, affecting the assembly quality of the locking front ring, or the clamping force is too large, which easily causes damage to the SF6 density controller during clamping. Summary of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide a clamping device for the locking front ring of a remote transmission type SF6 density controller, which realizes the clamping and positioning of the SF6 density controller by driving the clamping device to open and close through a cylinder, and the clamping force is stable and consistent, effectively ensuring the reliable clamping of the SF6 density controller.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamping device for the assembly of the locking front ring of a remote transmission type SF6 density controller, including a base plate, a pair of relatively spaced semi-circular rings are arranged on the base plate, and a circular cavity for accommodating the SF6 density controller is formed by enclosing the pair of semi-circular rings. A pair of clamping fixed blocks with opposite ends and intervals are arranged on one side of the semi-circular ring, and a cylinder is arranged on the other side of the semi-circular ring. A clamping moving block opposite to the pair of clamping fixed blocks is arranged at the telescopic end of the cylinder, and the cylinder is used to drive the clamping moving block to telescopically move to open and close with the pair of clamping fixed blocks to clamp the SF6 density controller.

[0007] Further, a fixing plate is arranged on the other side of the semi-circular ring, and the cylinder is arranged on the fixing plate.

[0008] Furthermore, at least one end of each of the semi-circular rings is arranged at a relative interval.

[0009] Furthermore, the inner circumferential surface of the semi-circular ring matches the outer circumferential surface of the SF6 density controller.

[0010] Furthermore, the inner circumferential surfaces of the clamping fixed block and the clamping moving block enclose a circular cavity for clamping the outer circumference of the SF6 density controller.

[0011] Furthermore, the inner circumferential surface of the fixed plate does not exceed the inner circumferential surface of the semi-circular ring on the other side.

[0012] Furthermore, a fixing rod for being embedded in the assembly table is arranged at the lower end of the base plate, and the fixing rod includes at least a pair arranged at intervals.

[0013] Furthermore, the inner circumferential surface of the fixed plate is flush with the inner circumferential surface of the clamping moving block.

[0014] Due to the above technical solutions adopted by the present utility model, it has the following advantages and effects:

The clamping device is opened and closed by driving a clamping moving block to move telescopically towards a clamping fixed block through a cylinder, ensuring the clamping and positioning of the SF6 density controller. Since the thrust of the cylinder is adjustable, the clamping force can be precisely controlled, and thus the clamping force is stable and consistent, realizing the reliable clamping of the SF6 density controller and avoiding the problems of easy damage to the SF6 density controller or poor assembly quality of the locking front ring caused by too large or too small clamping force.

The clamping is automatically controlled by a cylinder, reducing the labor intensity of workers and effectively improving the assembly efficiency of the locking front ring.

Detailed implementation manners

[0023] The embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, so as to more clearly understand the purpose, features and advantages of the present utility model. It should be understood that the embodiments shown in the drawings are not limitations on the scope of the present utility model, but only to illustrate the essential spirit of the technical solution of the present utility model.

[0024] As Figures 1 - 5 shown. The present utility model provides a clamping device for the locking front ring assembly of a remote transmission SF6 density controller, including a base plate 4. A pair of relatively spaced semi-circular rings 6 are arranged on the base plate 4. A circular cavity for accommodating the SF6 density controller 13 is formed by enclosing the pair of semi-circular rings 6. A pair of clamping fixed blocks 5 with opposite ends spaced apart are arranged on one of the semi-circular rings 6. A cylinder 1 is arranged on the other semi-circular ring 6. A clamping moving block 2 opposite to the pair of clamping fixed blocks 5 is arranged at the telescopic end of the cylinder 1. The cylinder 1 is used to drive the clamping moving block 2 to telescopically move to open and close or release the clamping of the SF6 density controller 13 with the pair of clamping fixed blocks 5.

[0025] Specifically, the base plate 4 is a circular plate, and the semi-circular ring 6 is a semi-circular strip-shaped block. The bottoms of the pair of semi-circular rings 6 are respectively fixed on the upper plate surface of the base plate 4 by first screws. The first screws pass through the base plate 4 from bottom to top to fix the pair of semi-circular rings 6 respectively. The outer peripheries of the pair of semi-circular rings 6 are located within the upper plate surface of the base plate 4. The circular cavity formed by the pair of relatively spaced semi-circular rings 6 is coaxial with the outer periphery of the base plate 4. The inner periphery of the circular cavity has a clearance fit with the outer periphery of the SF6 density controller 13 to facilitate the taking and placing of the SF6 density controller 13. The clamping moving block 2 is fixed at the telescopic end of the cylinder 1 by the fourth screw 8. The pair of clamping fixed blocks 5 are respectively fixed on one of the semi-circular rings 6 by the fifth screws 11.

[0026] Furthermore, a fixing plate 3 is arranged on the other semi-circular ring 6, and the cylinder 1 is arranged on the fixing plate 3. One end of the fixing plate 3 is fixed on the upper end surface of the semi-circular ring 6 by the second screw 9. The other end of the fixing plate 3 extends out of the outer periphery of the semi-circular ring 6. The cylinder 1 is arranged at the end of the fixing plate 3 extending out of the semi-circular ring 6. The fixed end of the cylinder 1 is fixed on the fixing plate 3 by a plurality of third screws 7.

[0027] Specifically, the fixing plate 3 is integrally formed by connecting an arc-shaped plate and a square plate. One end of the arc-shaped plate is attached to the upper end surface of the semi-circular ring 6 on the other side and fixed to the upper end surface of the semi-circular ring 6 through the second screw 9. One side of the square plate extends out of the outer periphery of the semi-circular ring 6 for fixing the cylinder.

[0028] Furthermore, in order to facilitate the placement of the terminal post 1301 of the SF6 density controller 13, at least one end of each semi-circular ring 6 is spaced relatively. When the SF6 density controller 13 is placed in the circular cavity formed by enclosing a pair of semi-circular rings 6, a pair of terminal posts 1301 on the outer periphery of the SF6 density controller 13 in the radial direction are embedded in the space between the pair of semi-circular rings 6, and the mounting posts 1302 on the outer periphery of the SF6 density controller 13 in the radial direction are embedded in the space between a pair of clamping fixed blocks 5 with opposite ends.

[0029] Furthermore, in order to facilitate the placement of the SF6 density controller 13 in the circular cavity, the inner peripheral surface of each semi-circular ring 6 matches the outer peripheral surface of the SF6 density controller. A clearance fit is formed between the inner peripheral surface of the semi-circular ring 6 and the outer peripheral surface of the SF6 density controller 13.

[0030] Furthermore, in order to facilitate the clamping of the SF6 density controller 13, the inner peripheral surfaces of the clamping fixed block 5 and the clamping moving block 2 enclose a circular cavity for clamping the outer periphery of the SF6 density controller 13.

[0031] Specifically, the clamping fixed block 5 is a pair of arc-shaped annular strip blocks. The inner peripheral surface of the clamping fixed block 5 is slightly smaller than the inner peripheral surface of the semi-circular ring 6 on one side, and the inner peripheral surface of the clamping moving block 2 is slightly smaller than the inner peripheral surface of the semi-circular ring 6 on the other side. The inner peripheral surfaces of the clamping moving block 2 and the clamping fixed block 5 relatively enclose a circular cavity for clamping the outer peripheral surface of the combined SF6 density controller 13.

[0032] Furthermore, in order to prevent the inner periphery of the fixing plate 3 from hindering the placement of the SF6 density controller 13 in the pair of semi-circular rings 6, the inner peripheral surface of the fixing plate 3 does not exceed the inner peripheral surface of the semi-circular ring 6 on the other side.

[0033] As a preference, the inner peripheral surface of the fixing plate 3 is flush with the inner peripheral surface of the semi-circular ring 6 on the other side. The inner peripheral surface at one end of the arc-shaped plate of the fixing plate 3 is flush with the inner peripheral surface of the semi-circular ring 6 on the other side, and the width dimension of the arc-shaped plate is the same as the width dimension of the semi-circular ring 6, making the inner and outer peripheries of the arc-shaped plate and the semi-circular ring 6 flush.

[0034] Furthermore, in order to facilitate the fixation of the clamping device, fixing rods 12 for being embedded in the assembly table are provided at the lower end of the base plate 4, and the fixing rods 12 include at least a pair spaced relatively. The entire clamping device is fastened in the table surface of the assembly table through the fixing rods 12, facilitating manual operation.

[0035] As a preference, there are three fixing rods 12, and the three fixing rods 12 are evenly arranged and connected to the lower end surface of the base plate 4. A screw hole is provided at the top of each fixing rod 12, a counterbore is provided on the base plate 4, and a countersunk head screw 10 is arranged in the counterbore and threadedly connected to the screw hole to fasten the fixing rod 12 to the lower end surface of the base plate 4.

[0036] Again, as Figure 5 shown. When the clamping device for the locking front ring assembly of the remote transmission SF6 density controller provided by the present utility model is specifically used: the device is fixed on the assembly table through the fixing rod 12, the SF6 density controller 13 is placed in a pair of semi-circular rings 6 on the base plate 4, a pair of terminal posts 1302 of the SF6 density controller 13 are embedded in the interval between the two ends of the pair of semi-circular rings 6, and the mounting post 1301 of the SF6 density controller 13 is embedded in the interval between the two ends of a pair of clamping fixed blocks 5. The switch handle of the cylinder 1 is pulled, the cylinder 1 extends, and the clamping moving block 2 fixed on the cylinder 1 moves to cooperate with the pair of clamping fixed blocks 5 to clamp the outer periphery of the SF6 density controller 13. Then, a locking front ring is assembled on the outer periphery of the SF6 density controller 13. After the assembly is completed, the switch handle of the cylinder 1 is pulled again, the cylinder 1 contracts, and the SF6 density controller 13 is taken out.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
