Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, specifically to a drilling device for valve flanges. Background Technology

[0002] When drilling holes in the flange of a valve body, ensuring the stability of the valve body is crucial. To achieve this, traditional methods often require fixing the upper and lower outer walls of the valve body. However, this fixing method usually requires multiple independent drive devices to work together, which not only increases the complexity of control but also significantly increases the cost of the entire equipment. Therefore, we propose a drilling device for valve flanges. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a drilling device for valve flanges to solve the above-mentioned problems in the prior art.

The drive post is inserted into the push groove to drive the clamping arm to deflect synchronously.

[0008] Furthermore, the lower drive ring has an arc-shaped groove, and the bottom of the lower clamping ring has an extension block connected to the support base. The extension block passes through the arc-shaped groove so that the drive ring can rotate relative to the clamping ring.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See attached document Figure 1-4 A drilling device for valve flanges includes a support column 1, a lifting seat 2 that can move up and down along its direction on the support column 1, mainly used to adjust the height of the drilling position according to the actual situation. The specific structure is prior art and will not be described in detail in this application. A support seat 3 is provided on one side of the lifting seat 2, and a clamping mechanism is provided on the top of the support seat 3 for clamping the valve body of the valve.

[0023] The clamping mechanism includes a drive unit and a clamping unit. The drive unit includes a pair of drive rings 41, and several vertical rods 42 are connected between the pair of drive rings 41 so that the two drive rings 41 move synchronously. Several drive arms 43 are provided circumferentially on the inner wall of the drive rings 41, and a drive post 44 is provided on one side of the drive arm 43. The clamping unit includes a pair of clamping rings 51, and several connecting rods 52 are connected between the pair of clamping rings 51. Several clamping arms 53 are provided circumferentially on the inner wall of the clamping rings 51. The clamping arms 53 are provided with push grooves 54 that cooperate with the drive post 44. The drive post 44 is inserted into the push groove 54 to drive the clamping arms 53 to deflect synchronously.

[0024] 3. In use, place the valve body into the middle position of the clamping ring 51. When the drive ring 41 is rotated, the upper and lower drive rings 41 will rotate synchronously under the action of the vertical rod 42. This further causes the upper and lower drive arms 43 to drive the upper and lower drive columns 44 to move synchronously. At this time, the upper and lower clamping arms 53 can clamp the upper and lower sides of the valve body at the same time, improving the clamping efficiency. Through the coordinated work of the upper and lower clamping arms 53, the upper and lower sides of the valve body are clamped, which significantly improves the efficiency of the clamping operation. Through a unified drive mechanism, the upper and lower clamping arms can respond at the same time, without the need to configure separate clamping systems, thereby effectively reducing equipment costs and simplifying the operation process.

[0025] In this embodiment, an arc-shaped groove 45 is provided in the lower drive ring 41, and an extension block 55 connected to the support base 3 is provided at the bottom of the lower clamping ring 51. At this time, the clamping ring 51 is fixed and cannot move, so as to avoid the clamping unit shaking during the clamping process and affecting the clamping effect. The extension block 55 passes through the arc-shaped groove 45 so that the drive ring 41 can rotate relative to the clamping ring 51, thereby ensuring that the drive unit can rotate relative to the clamping unit and form a clamping of the valve body.

[0026] In this embodiment, the push groove 54 is an arc-shaped structure, and the distances from the center of the clamping ring 51 at both ends are different, so that when the drive column 44 pushes the clamping arm 53, it can generate a gradually increasing clamping force, which helps to fix the valve body more firmly.

[0027] In this embodiment, a first motor 6 is provided on the top of the support base 3. A gear 7 is connected to the output end of the first motor 6. The outer wall of the lower drive ring 41 is provided with teeth 46 that cooperate with the gear 7, so that the gear 7 can drive the drive ring 41 to rotate. When the first motor 6 starts, the gear 7 rotates and drives the drive ring 41 to rotate through the teeth 46, so as to complete the clamping and fixing operation of the valve body.

[0028] In this embodiment, a drilling box 8 is provided at the top of the support column 1, a second motor 9 is provided at the bottom of the drilling box 8, a drilling arm 10 is connected to the outer wall of the output end of the second motor 9, a third motor 11 is provided above the drilling arm 10, and a drill bit 12 is connected to the output end of the third motor 11. When the third motor 11 is started, the drill bit 12 rotates to perform drilling operations. When the second motor 9 is started, the drilling arm 10 drives the drill bit 12 to rotate around the axis of the output shaft of the second motor 9. At this time, the circumferential drilling operation of the valve body flange can be completed without adjusting the position of the valve body back and forth, which greatly improves the drilling efficiency.
