Description

Technical Field

[0001] This utility model relates to the technical field of valve cover tightening machines, specifically valve body and valve cover tightening machines. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. However, regardless of the type of valve, all of its components include a valve cover, which is mainly fitted onto the valve stem to seal the valve body after the valve stem is installed.

[0003] Traditional valve body and cover tightening equipment often lacks precise positioning devices or has a simple positioning structure, failing to effectively guarantee the relative positional accuracy of the valve body and cover before tightening. Relying solely on simple mechanical structures to place the valve body and cover is prone to misalignment during tightening, resulting in a loose fit between the cover and the body, poor sealing performance, and increased risk of leakage. This negatively impacts the overall quality and performance of the product. Without precise tightening process control, such as using ordinary motors or simple pneumatic devices, it's difficult to achieve accurate torque and rotation angle control. This can lead to over- or under-tightening of the cover. Over-tightening may damage the threads of the valve body or cover, shortening product lifespan; under-tightening will compromise the sealing effect, easily causing leakage during use. Therefore, we have introduced a valve body and cover tightening machine. Utility Model Content

[0033] The side of electrical control box 1 is connected with side plate 3, and the side of electrical control box 1 is fixedly connected with side plate 3, and the top of side plate 3 is connected with button 4.

[0034] One side of the top of machine case 9 is connected with alarm lamp 10, and alarm lamp 10 can send alarm signals when abnormal conditions occur during equipment operation.

[0035] The bottom of electrical control box 1 is connected with base 2, the bottom of base 2 is provided with anti-skid lines, and the anti-skid lines can make electrical control box 1 more stably placed on the ground.

[0036] The side of connecting seat 11 is connected with reinforcing rib 12, and the reinforcing rib 12 of the side of connecting seat 11 enhances the structural strength of connecting seat 11, ensures the stability of the equipment during operation, the base 2 at the bottom of electrical control box 1 provides a stable support foundation for the entire equipment, and prevents the equipment from shaking during operation.

[0037] The safety grating 18 is connected between the electrical control box 1 and the machine case 9, the safety grating 18 is connected between the electrical control box 1 and the machine case 9, when an object blocks the safety grating 18, the equipment will stop running immediately, to prevent the operator from being injured during equipment operation, and to protect the personal safety of the operator.

[0038] The bottom side of the pneumatic rotary clamp 7 is provided with a hydraulic cylinder 72, and the output end of the hydraulic cylinder 72 is connected with a clamping block 71.

[0039] The top of the clamping block 71 is connected with a sliding block 74, and the inside of the pneumatic rotary clamp 7 is provided with a sliding groove 73 for slidingly connecting the sliding block 74.

[0040] Specifically, in use, the valve body is placed on the clamp 5, and the valve body is preliminarily fixed and positioned by the clamp 5 to ensure that the position of the valve body is stable in the subsequent operation. The connecting seat 11 is located inside the top case 9 of the electrical control box 1, and the top positioning column 13 cooperates with the positioning sleeve 17 to provide an accurate positioning reference for the side T-shaped fixing seat 8. One side of the side T-shaped fixing seat 8 is connected with the positioning sleeve 17 and the positioning column 13 to ensure the position accuracy in the vertical direction.

[0041] The valve cover is placed on the floating tightening jig 6, and at this time, the valve cover is in a state of waiting to be tightened. The cylinder 14 starts to work and pushes the top plate 15 to move upward. Since the bottom side of the top plate 15 is connected with the servo system 16, the upward movement of the top plate 15 drives the entire tightening mechanism to move upward, so that the pneumatic rotary clamp 7 approaches the valve cover.

[0042] After the pneumatic rotary clamp 7 approaches the valve cover, the hydraulic cylinder 72 is started, and the output end of the hydraulic cylinder 72 starts to stretch and push the clamping block 71 connected thereto to move. The sliding block 74 at the top of the clamping block 71 slides in the sliding groove 73 inside the pneumatic rotary clamp 7. This sliding connection structure ensures that the clamping block 71 maintains a stable straight line movement direction during the movement and cannot deviate or shake. With the continuous stretching of the output end of the hydraulic cylinder 72, the clamping block 71 gradually approaches the workpiece until it contacts the workpiece and applies a clamping force to firmly clamp the workpiece in the working position. When the machining is completed or the workpiece needs to be replaced, the output end of the hydraulic cylinder 72 starts to contract. Under the cooperation of the sliding block 74 and the sliding groove 73, the clamping block 71 moves reversely along the sliding groove 73 stably and away from the workpiece, so as to release the clamping force on the workpiece, and the workpiece can be conveniently taken out or replaced. During the entire machining process, the clamping action of the clamping block 71 driven by the hydraulic cylinder 72 cooperates with the rotating action of the pneumatic rotary clamp 7 to realize effective control of the workpiece in terms of clamping and position adjustment, ensuring the smooth progress of the machining process. The valve cover is clamped to ensure that it does not deviate during the tightening process. At the same time, the servo system 16 is started to drive the pneumatic rotary clamp 7 to rotate. Under the rotating action of the pneumatic rotary clamp 7, the valve cover starts to rotate relative to the valve body. Since the floating tightening jig 6 is connected to the clamp 5, and the clamp 5 fixes the valve body, the valve cover is gradually screwed on the surface of the valve body. In this process, the floating tightening jig 6 can float within a certain range to adapt to the possible positional deviation between the valve cover and the valve body, ensuring the smooth progress of the tightening process.

[0043] The operator controls the whole screwing process through the button 4 on the top of the side plate 3, such as starting, stopping and other operations, the alarm lamp 10 on the top of the machine box 9 can send an alarm signal when an abnormal situation occurs during the operation of the device, for example, the screwing force is too large or too small, the component movement is abnormal, etc., the safety grating 18 is connected between the electrical control box 1 and the machine box 9, when an object blocks the safety grating 18, the device will immediately stop running, preventing the operator from being injured during the operation of the device, and protecting the personal safety of the operator, the electrical control box 1 controls the electrical system of the whole device, coordinates the actions of each component, and ensures that the device works according to the predetermined program and parameters, the reinforcing rib 12 on the side of the connecting seat 11 enhances the structural strength of the connecting seat 11, ensuring the stability of the device during operation, and the base 2 at the bottom of the electrical control box 1 provides a stable support foundation for the whole device, preventing the device from shaking during operation.
